Opera does not complete to load the webpage

Opera does not complete to load the webpage

Hello, many times Opera does not terminate to load the webpage and shows the number of pending elements as you can see in the image. Net settings are as default. I also tried different but nothing changes. This does not happen all the time but frequently.

Do you know what can I do?. Thanks.

You seldom see it mentioned because it was only a checkbox in versions up to and INCLUDING version 11.01. So, this is new with version 11.11 -- now you can select specific values.

Unless I'm misunderstanding something, he did mention it (or I wouldn't have posted back here), although his terminology was not precisely Opera's:

I used Opera's terminology instead in my post above: Max Connections Server and Max Connections Total... ...and both settings are available in both 11.01 and 11.10 (as is a checkbox to Reduce Max Persistent HTTP Connections that I assume is the checkbox you mentioned). In fact, I just checked my 10.63 and 10.70 installations and they are both in there as well, but they're not in my 10.62 installation. So looks like they've been around a while.

(I haven't been able to find any setting labeled Max Persistent Connections Server, but I've been assuming you mean Max Connections Server.)

Glad your setup is working so well after all the efforts and frustration of the past few months!

BTW, I tried visiting http://stevesouders.com/hpws/max-connections.php a few times, and I'm wondering what to expect, both in terms of the number of images loaded and the time it takes to load them.

================================================================
Under the Performance section it says
Max Persistent Connections Server (which I think is per server)

which is at 6, I think thats what he's talking about, but have seen no difference in changing it.

I don't understand what that stevesouders image load is suppose to mean either.

Interesting, when I lowered Max Persistant Connections Server to 4 it does seem to show a faster smoother download on the Progress Bar.

I tried it at 2, it was fair, but at 4 seems to be more efficient.

It does seem to act a little weird to fetch newsgroup posts.

I read articles on this setting at Wikipedia, Microsoft TechNet, various University sites, W3C site, all seem to say maximum persistant connections help keep alive the connection so other elements on the page load without each one making a separate connection to be less stressful on servers overloading the web which leads to hackers DDOS.

But all the latest Browsers have this setting to 6 when it used to be 4.
Then you have to consider if Pipelining is used which changes things again.
and if a server uses HTTP 1.0 or HTTP 1.1

Need a technical expert to really understand the inner workings of this.

Hello sibelius (and all), thanks for starting the tread. This issue drives me absofucinlutely nuts! I saw <a href="http://my.opera.com/desktopteam/blog/show.dml/30305892?startidx=50#comment61135092">this</a> post on the Desktop Team blog today, and replied <a href="http://my.opera.com/desktopteam/blog/show.dml/30305892?startidx=100#comment61154672">back</a>.

Lukas has a blog <a href="http://my.opera.com/lksd/blog/2011/05/09/opera-11-50">here</a> pertaining this issue, & ayespy has similar issues and you can see my return comments that reflect these issues as well. Its great to see people come together to attempt to resolve these issues, but in all honesty its also really disheartening to read all the "fixes" from users while Opera is once again invisible regarding the matter.

Ive had fits since Ive started to tether via a 3G phone. For some reason at times Opera does not finish loading tabs (even though the blue dot notifier states IT IS finished loading), at times Opera automatically reloads tabs when I move from one tab to another tab thats already loaded(yes, "Check Documents" setting is set to every hour), at times when I click the "stop button" to stop the tab from reloading, it auto reloads (faster than my fingers can click AGAIN to stop!). It just acts wonky. My only other alternative is Safari, which never has any of these issues.

I suppose Java Scripts is buggy, but its not an alternative to keep it turned off. I see no real improvement in tweaking Max connections either, and ive loaded up my urlfilter with all listed above (and Fanboy's).

Where is Opera's advice and guidance in all of this?

How does Opera support slow connections/latency, and where is this "set up" information located on Opera.com?

Is it assumed that all users are utilizing WiFi and not 3G or other alternatives?

Ive looked around the forums and its very evident that Opera <a href="http://my.opera.com/community/forums/topic.dml?id=964452">is</a> <a href="http://my.opera.com/community/forums/topic.dml?id=491741&t=1305834503&page=1#comment9367522">missing</a> <a href="http://my.opera.com/community/forums/topic.dml?id=900351&abc=&page=2&skip=50&show=&perscreen=50">in</a> <a href="http://my.opera.com/community/forums/topic.dml?id=879912">action</a> regarding this well known issue.

Cheers!

I tried another setting that seems to be "overlooked" by many with n-1 hangs.

After all the tweaks especially the "Maximum Persistent Connections per server = 4"
I tried various settings of the, "Preferences" "Browsing" "Loading" and set it to "Redraw when Loaded" instead of redraw after 1 or 2 seconds as before.

I noticed that instead of seeing the screen redraw the page 3,4,5, or more times to add elements to it and correct it, that when set to "Redraw when Loaded" gave a full page draw without all the repositioning of the page.

It didn't slow down anything connection wise,
it just seems to be a smoother display when all the information is "decoded" by the CPU to the Browser this way rather than each piece of data thrown on the screen one by one.

I see the progress bar "jump" in numbers to the total rather than all the counting.

This could possibly help too with stopping n-1 hangs with more data being processed in order instead of pieces.

Since the last two versions (after making the Max Persistent Connections Server changes) I've not seen n-1. Everything loads just fine. "Redraw when Loaded" might make the presentation smoother. I haven't played with that since waaaay back in a far and distant galaxy. Actually, pages load pretty darn fast on my machines. They just seem to expode onto the screen. I supposed it might depend on the site; some sites have all kinds of stuff to load. I think I miss most of those with my hosts file.

With Opera 11.50 I'm able to access some sites that really gave me problem (university Blackboard system); all working fine. 11.50 really is faster.

thats good

Greetings

Which are the latest tricks? Max Persistent Connections Server=4 and "Redraw when Loaded"? I will apply them.

Opera 11.50 is giving me problems besides n-1.

Thank you, all of the researchers whom have posted (above). I found an earlier post on this issue and it had this suggestion:

open opera:config

Open "Performance" item

Change "Network Buffer Size" from 128 to 32

This is what I did and it fixed the problem! After all this time putting up with the problem and even going back to IE (how horrible is that?), it is now fixed. Yay!

Curiously, a subsequent post suggested changing the same setting from 128 to 4096 and it worked for that user. What it does is a mystery to me, but as long as it works, who cares?

THANK YOU!!!! wow...i made this change and opera is now usable again!!!

I'm having a lot of maddening problems with Opera, including n-1. Problems have persisted through at least one major version change (10 to 11). Wondering if it's time to try a different browser again.

Anyway, I'm not so sure that hobbler's instructions for changing MTU in Windows are necessarily correct. I think the value of the HKEY_Local_Machine\System\CurrentControlSet\Services\NdisWan\Parameters\Protocol\0\ProtocolMTU key may only apply to the Windows PPPoE client. If you're connecting through a router which is the PPPoE client I'm not sure that setting will work. In that case I believe these may be the correct settings to change (method 2 / 3): KB900926: Recommended TCP/IP settings for WAN links with a MTU size of less than 576. (Not sure if method 2 is required in order to use method 3.).

I'm not 100% sure about that, but see here for more info.

I am sure I don't block anything on allmusic.com but only after disabling the hosts file does it load properly.

I'm still thinking I remember something about sometimes the final elements that don't load are failing to be retrieved by the site's server (e.g., allmusic.com) from some other remote server (e.g., web statistics counters), sort of a "third-party" element... ...or poorly-designed webcounter scripts mentioned by sgunhouse. In those cases, what you do/don't block wouldn't be a factor.

But recently I began wondering if the urlfilter.ini or Hosts file could perhaps block such a "third-party" element if the remote server's URL were blocked by the filter? I'm guessing not, but I'm not clear enough about how everything works together to know if that is even possible. So can you (bartgzn) or janusz maybe clarify that a bit for me?

Thanks!

@janusz: It's been fun walking through all of this with you, and your last post above is especially informative.

I don't know why I'm NOT having any of the n-1 problems, but if/when I encounter them, I know where I'll turn (these threads where we've been carrying on), and who I'll turn to (hint: look in the mirror).

First, just to be clear, I'm not having any (n-1)/n problems, and never really have (i.e., no wink, wink on my end). In fact, I have to keep reminding myself that you and others are actually experiencing (n-1)/n hangs because all I ever see are occasional pages where I just click the Stop Loading button and go on never thinking anything more about it.

But since our extended interactions I've been following all of your posts to others about the (n-1)/n problems, so I feel like I've been a companion on your journey, and continue to be interested in how your answers work out for others (and for how many). So I just had to jump in where I did above because your post just preceding mine summarized some of your key findings so well, and I wanted to give you that feedback (as well as flag it for my own potential future use).

Originally posted by janusz:

Say, I think you use a different hosts file than I do -- hphosts?

No, I'm not using a Hosts file at all (you may recall my questions about whether the Hosts file functions more-or-less like a system-wide urlfilter.ini) ... ...Even though I've know about them for at least 8-10 years and have been pretty security conscious, I have yet to try using a Hosts file. But when I get around to it, I plan to follow your HostsMan with HostsServer suggestion as a good place to start.

Originally posted by janusz:

Do you use anything to replace the action canceled, navigation error, the red-X, etc. the show up in the places that ads were blocked? If you do then it may be that the image fulfills the vacant slot and you never see it or know it is there. As mentioned, I use HostsServer to replace the messages with a tiny transparent image. Some websites use "IFrame" and HostsServer solves the problem and cleans up the page for nice viewing.

AFAIK, I don't have any kind of placeholder for blocked elements, except Flash/Shockwave elements that are blocked by my Flash Block UserJS (until I click on the placeholder). It seems if I were having the (n-1)/n hangs, it could be very useful as part of trying to investigate. But if I'm not having the hangs, is there some other benefit? Do you have a good example of an IFrame site I can check to how it renders on my setup?

But I don't recall that I ever mentioned what I use (besides urlfilter.ini) in our previous discussion, let alone summarize it in one place. So here's a summary (not that much, really):

---urlfilter.ini [Fanboy's Adblock list for Opera (with Stat & Tracking Sites) ["Note: May cause false positives on some websites" (i.e., pretty aggressive)]
---UserJS: Lex1's AdBlock+ v1.3.12
---UserJS: Lex1's Flash Block v1.3.15
---UserJS: Lex1's Hide js-popups v1.0.6
---UserJS: ExpertsExchangeFilter (not really relevant, but included in the interest of completeness)

I think sibelius mentioned that rebooting seems to work sometimes. Yes, that was my experience also. Clearing private data did nothing but reboots (yes, more than once) somehow forced Opera to "clear the decks" to permit loading of the site w/o hangs. Again, I think it has to do with sequential loading by Opera in some way.

Yeah, this finding is vaguely troubling to me. I can't see any reason a reboot should be necessary. From my understanding, it seems at most, clearing the cache, maybe deleting all private data (?), and restarting Opera should be sufficient. So this puzzles me.

If you have reinstalled Opera into its own folder (i.e., Opera 11.01; d/l Opera to local folder and install from the folder instead of running it as it downloads from the server) and none of this seems to work, I would look for other things ...

Ever since I started using Opera, I always install each new version to its own folder (and I've probably recommended a fresh install in a new folder in at least 2-3 dozen threads in just the last month ). But as I stated above, I'm not having any (n-1)/n problems (who knows? ...maybe those new folder installs have been one of the reasons).

You mentioned this CSS file in your thread, and I never followed up on it, but I take it the custom Win XP css file is something different. If so, what are each of them basically set up to do (e.g., compared with the installed default opera.css, if that is the relevant comparison).

Originally posted by janusz:

I thought, "How wonderful. I get to find another entry to delete in the hosts file." No such luck. It loaded within about 8-10 seconds. It now loads in microseconds. Darn it. No more n-1 hangs. Sorry about that; I couldn't help myself.

Guess you miss the adrenalin of all that detective work.

Jeez, I turn my back for half a day, and when I come back I have to read a dang book!!!
(...might be how some feel about my posts )

FWIW, I keep the following 2 commands in my Run list, and I never even thought to mention them before in all the discussion about loading lags. But if I run into a stretch where things seems to be lagging or bottle-necking (pages not loading, music stream continually being interrupted, etc., I routinely run both:

cmd /k ipconfig /flushdns
cmd /k netsh interface ip delete arpcache

I like having them set up this way because the command window persists and I can see that it actually has completed. If I'm in a hurry to do other things, I just proceed with my work and check the window later when I think about it. But I don't use a Hosts file, so I rarely see it take more than 5-10 seconds for either.

I didn't realize this might have anything to do with this discussion (and I don't know if the arpcache does). But I first ran across these 2-3 years ago when it became apparent that my 24/7 music streaming was involved in frequent crashes of our wireless router. I don't recall the exact details anymore, but as I recall it had more to do with the arpcache and is somewhat common with streaming over wireless routers. So I got in the habit of running both commands as often as I thought of it (tried for at least daily), and wireless router crashes became almost non-existent. But it was still a hassle, and eventually I switched back to the hardwired network for my desktop: now I rarely have to reset DSL modem and router (don't really even know which crashes).

A reboot will automatically reconnect using a different IP address (of course I can accomplish the same thing with a disconnect/reconnect of the connection), so sometimes this fixes the very slow page loading time of that forum. I have noticed no problem with IP addresses 32.176.xxx.xxx, but oftentimes have problems with IP addresses 166.183.xxx.xxx. Note that other web pages and forums load normally with either IP address. The offending forum happens to be the carrier's forum for my cellular WWAN service!

Verrry interesting! It seems there is no end to the complexity of the total picture and the number of factors that may come into play! Just when you think you've thought of just about anything and everything that could be involved, up pops another one (or six!).

Originally posted by janusz:

Other info: earlier I commented that I had read (somewhere in these forums) that too many open sites/tabs could cause n-1 incomplete loading of site pages. I did an experiment. I generally have about 15-2- open sites/tabs and have had no obvious difficulty. So, I added 10 additional tabs and added more to Speed Dial (10 total). I then restarted. Sure enough, n-1 errors on 4 sites. Reboot and still a problem. I then deleted those additional sites (18 open sites/tabs; 5 on Speed Dial) and restarted. All worked well. I did the same with FF: added 25 sites/open tabs -- all loaded fast and complete. Added 10 more; still all loaded fast and complete.

I can only guess that with the large number of site loading simultaneously that Opera runs into problems if a javascript request does not receive immediately response and it just keeps on waiting. Regardless, keeping open sites/tabs/Speed Dial to a maximum total of 18-20 or less should improve performance.

Just to throw a little more confusion into the mix, I regularly run 30-45 open Opera 11.01 tabs with no (n-1)/n problems. And the only reason I don't run more is that my P-III 733 MHz 512 MB RAM machine starts choking with more (another program or a new Opera tab/window doesn't open at all, or only after long delay, 100% CPU, etc.). Then I just close a few tabs and proceed normally.

Edit: I think I unintentionally confused things by starting my remark with "Just to throw a little more confusion into the mix..." That was meant to be tongue-in-cheek about this whole long process and sometimes confusing process you've been through in sorting out the n-1 issues.

My intended meaning would have been clearer if I had just said I regularly run way more tabs than the 18-20 max you suggested, probably in the same range as when you added the 10 tabs and 10 speed dials, but the choking I start to encounter when I go above that still doesn't result in the n-1 problems (presumably, based on your findings, because I'm not using a Hosts file).

Originally posted by janusz:

What the tabs reveal, if that is the word, is that somehow a squeezed bandwidth (with all those site loading), unlike previous versions (pre-Opera 10), causes n-1 problem. BTW, this is the first time I have been able to duplicate n-1 by choice and corrected it by choice -- an n=1 experiment.

OK, so I *think* there are 3 factors interacting in what you're hypothesizing about the number of tabs:
(1) number of tabs (of course )
(2) using a Hosts file
(3) "squeezed bandwidth" when you start Opera
(which, of course, I experience too, with longer loading times for some pages, but still no n-1 hung pages)

If I understand your hypothesis then, the Hosts file is limiting either the total number of tabs you can run, or at least the total you can open at once when starting Opera. (Or vice versa, I can either run more total tabs without the Hosts file, or at least open more tabs all at once when I start Opera.)

So what if you start Opera with a low enough number of tabs to avoid activating the n-1 hangs (e.g., 1-15 tabs), then add tabs one at a time. Are you then able to open a considerably higher number of tabs (e.g., as many as with FF)?

Sorry, I think I wasn't clear enough with my question.

I didn't say or ask anything about the cause, except to quote your statement that

Originally posted by janusz:

What the tabs reveal...is that somehow a squeezed bandwidth (with all those site loading), unlike previous versions (pre-Opera 10), causes n-1 problem.

And I think I understand well enough your theory about the cause. But my question isn't about the cause (except indirectly insofar as the number of tabs may play a role in creating the n-1 conditions, or triggering the n-1 cause).

I was trying to clarify what you discovered about the max usable tabs without n-1 hangs and your hypothesis as to why the n-1 hangs occur with too many tabs. And more specifically, whether the max tabs is roughly equal during startup and ongoing browsing, or lower at startup (because they are all loading at once) than during ongoing browsing.

You said you added 10 tabs and 10 Speed Dials and restarted Opera, and had 4 pages with n-1 problems (but that is with all those pages reloading at once during an Opera restart). However, if you reduce to around 18-20 tabs max, you get no n-1 problems at restart. So I was asking whether you will also start getting n-1 problems around the same number of total tabs if you start Opera with 18-20 tabs and then gradually add maybe 10-15 more tabs... ...or would your max tabs be substantially higher before encountering n-1 problems as long as they are added gradually.

(BTW, my assumption throughout the entire discussion has been that you could encounter an n-1 page at any time, not just at restart. Is that incorrect?)

As I post this, I realize that even though you mentioned "squeezed bandwidth" in your hypothesis, I wasn't actually thinking about bandwidth so much as your hypothesis that something in Opera's sequential loading isn't playing well with the Hosts file, especially if the number of tabs is too high. But my question is an empirical one: whether you observe the number of tabs necessary to start triggering n-1 problems is the same at startup and during ongoing browsing, or if you find that your tab count can actually go much higher before starting to see n-1 problems if the tabs are added gradually after the restart.

I hope that's clearer now, but I'll have another look at it after I get some sleep and can think clearer.

(As mentioned above, I don't seem to get the n-1 hangs, but I keep following the thread, and)...

FWIW, I have the Fraud Protection enabled and all of my Avast! real-time shields enabled as well (including the web real-time shield), and I've never noticed any conflict between them.

(I've also never had the Fraud Protection flag anything yet that I can recall. So I'm not at all clear what it's doing, or if it's doing anything at all.)

The Firefox hangs link http://support.mozilla.com/en-US/kb/Firefox%20hangs mentions the P4 hyper-threading problem only in reference to hangs loading the first window, so I don't know if it is or isn't relevant.

But the method they suggest for WinXP is to simply change the properties for the shortcut you use to start Firefox (or Opera) to run in Win98_Me Compatibility Mode... ...an easy thing to try, and easy to reverse.

Hosts file may indeed block it but Opera still looks for that ONE something and the local content blocker kills the wait and n-1 never appears. My brain is fried on this stuff.

Whatever...I tried to coax n-1 out of the woods with all those open tabs. As I open each, they loaded fast and complete. I restarted several times, rebooted several times. No n-1.

Yeah, well my Google/elephant remark was just an opportunity to make a little joke out of this brain-frying journey.

But this is actually the first time in a long time that you've been able to post anything that sounds like such a pronounced change with such a clear-cut methodology. Admittedly it hasn't yet stood the test of time, but it seems encouraging and hopeful!

And you've been remarkably patient, persistent, and active in seeking solutions. If it was me, I'd be pretty persistent, but no way I could match your energy/activity level and the amount of exploration/experimentation and write-ups you've accomplished.

BTW, I know you want the Hosts file for other browsers, but I can't recall if you've tried temporarily taking the Hosts file out of the Opera equation and just using the urlfilter.ini (plus maybe AdBlock UserJS).

In fact, I just checked my 10.63 and 10.70 installations and they are both in there as well, but they're not in my 10.62 installation. So looks like they've been around a while.

(I haven't been able to find any setting labeled Max Persistent Connections Server, but I've been assuming you mean Max Connections Server.)

Glad your setup is working so well after all the efforts and frustration of the past few months!

BTW, I tried visiting http://stevesouders.com/hpws/max-connections.php a few times, and I'm wondering what to expect, both in terms of the number of images loaded and the time it takes to load them.

Go to Performance tab or just enter "Max Persistent" in search and, like magic, it's there!

I hate this!

I did exactly that, using "max" or "persist" as my search terms several times in both 11.01 and (I thought) 11.10! Also just looked at the whole Performance section in both 11.01 and (I thought) 11.10! ...But somehow I never found the setting in 11.10...
...And yet there it is, plain as day!

Reminds me of umpteen times my Dad would send me to the toolbox for a certain tool...
...which I couldn't find...
...so he would crawl out from under the car, go to the toolbox, and find the tool sitting right there on top of the other tools !!!

1b. Want to disallow persistent connections?
"No Connection Keepalive" (also under Performance) will allow or disallow persistent connections. Default=allow

Are there any circumstances you're aware of where this would be preferable or necessary?

2. The Steve Souder's image site.
Read the brief intro. If your browser is fast and loading all site images, then you can see images explode in view right before your eyes. If not, you will see incomplete loading (I don't recall what that looks like since everything loads for me in a couple of seconds). Just a nice visual check. Really comforting to see after messing with this for so long.

So if you put your Max Persistent Connections Server back to 6, does this page not load (i.e., n-1) or does it load load slowly or poorly?

I probably don't understand this correctly, but AFAICT this page would seem to pertain to Max Connections Server rather than Max Persistent Connections Server. And it seems the only way to use the page to discover the upper limit for Max Connections Server supported by a browser is to load the page while using a packet sniffer so you can count the number of simultaneous requests.

(BTW, the explanation on the web page seems inadequate on its own, but the exact same explanation made somewhat more sense to me when I ran across it again in the larger context of this stevesouders.com Roundup on Parallel Connections, which does also touch on the max persistent connections issue.)

In any case, I visited the page a couple days ago and again today with both Opera 11.01 or 11.10. In both Opera versions on the first visit to the page all 180 images load, with times ranging from 16 sec to 22 sec,* considerably more than the "couple of seconds" you're getting. However, when I reload the page, I never get all 180 images in either Opera version. In those cases, the "Page load time" can be more or less than the full 180 image load, but seems rather arbitrary, since it stops loading before all the images are loaded, and there is no explanation for why it stops when it does. I've only tried one change in the 11.10 Max Persistent Connections Server so far (from 6 to 4), but didn't notice any change fro better or worse.

*(This seems slow to me, but is with my system pretty maxed out and hasn't been rebooted since April 19, so overall performance is pretty laggy. In addition, Opera 11.01 has been running 24/7 since April 19 without a restart and 11.10 has been running since April 28, so neither is probably at peak performance. I hope to get to a place tomorrow where I can restart both, and I'll try again after that.)

A Shameless bump...

Ok, so I've often noticed, that when I run into problems with youtube (yes, I do run into problems with many other sites too) i.e. it hardly loads, or doesn't load at_all, I see this:



Why is Opera doing this? Even if I disable the persistent storage thing, after a little while it will still display some sites using it. And clearing the cache has resolved my issue at least with youtube.
