Opera 9 Not As Fast?
I have been an Opera user for years and am currently using Opera 9. It does seem consideably slower on page loading than previous versionsI also have Firefox with some tweaked settings which is considerably faster on page loading. This is astonishing because Opera was always way ahead. I know this kind of issue is somewhat subjective, but has anyone else noticed a definite slowdown Opera's performance?
Failing that can anyone suggest a list of action points for me to follow to check out what might be causing such a slowdown. I am on 512k broadband and have the following spec
1600ghz Athlon processor
512DDR ram
Win XPSP2
Comodo firewall
GesWall
AdAware
Windows Defender
Process Guard
Ewido
Spybot
All browsers function through DropMyRights
Thanks
Terry
Opera 9 has proven slower to load as an application, slower to load pages and constantly has to think about it before scrolling. Never had these problems with v8 and a test downgrade at the weekend shows that I still don't.

. firewall and/or antivirus - can interefere with any program - even Opera
. try a new, fresh profile/installation - upgrading from 8.x has been known to cause some problems
Opera 9 is running as fast as 8.x here.
First i did an Update of my 8.54-installation. Then Opera literally took ages to start up (more than 30 seconds). Also various things were not as they're supposed to. Scrolling did not work very smooth, it really seemed to think about it before doing it

Now, with a clean install it is very compareable to Opera 8.
- Josie Long
I cannot say I notice any difference. It remains slow and a bit hesitant to load up pages by comparison to a slightly supercharged Firefox.
Let me be clear I am an Opera fan not a Firefox aficionado. Until Opera 9 came out I would not have looked at Firefox. But on my set up for what ever reason Opera 9 is slow. When I say hesitant I mean as the page loads the items loaded are "clocked". Sometimes the clock almost stops sometimes it stops at two or three items short ie 57 out of 60 loaded.
I thank everyone for all their help and time expended in replying.
Any other suggestions gratefully received
Terry
ps as I said in previous posts I have Comodo Personal Firewall and Avast A/V Process Guard and others along with GESWALL

Yes I did delete my previous Opera Profile.
In terms of your comments about "Also, is your firewall / proxy server / anti-virus configured to allow Opera 9 through?" I am not clear what you mean. I am using Comodo firewall and Avast Home. The latter I have used for years when Opera was the fastest browser. I confess to migrating from Look n Stop to Comodo firewall. I used L n S when Opera was good and when it appeared to deteriorate. I have noticed NO SIGNIFICANT PERFORMANCE LOSS since migrating to Comodo. In other words Opera 9 was poor with L n S as with Comodo.
Both firewalls appear to work with Opera so I am a bit confused at what I have to do to allow Opera through, given that it is working. Can you be more specific please
Again thanks to all for your comments keep them coming
I just wish YOU ALL COULD SEE THE PERFORMANCE DIFFERENCE BETWEEN OPERA 9 & FIREFOX
Thanks again
Terry

If it does not help, you should try disabling your security programs one by one until the problem is solved. Then you know which program causes it.
As a former forum mod for an international AV app, I can tell you multiple firewalls and multiple on-access scanners are not a bad idea. They are a REALLY BAD idea. They do not increase your security, but decrease it by interfering with each other, and blocking each others' actions, and make your computer and its other apps buggy to boot.

Opera 9 is doubtlessly slower than 8, but the difference is as small as it must be. On modern equipment it should be hardly noticeable; even on older equipment the difference is hardly an issue.

Thats the kind of logical argument I can buy.
Even so in this case it won't wash. The speed difference in page loading between Opera and Firefox + Fasterfox tweaking is significant. I've timed it. Also if you look at the posts in this and other forums, not all but many, there is too much conformity to ignore. Forget all the rubbish about antivirus and firewalls etc. I have followed all the advice and more in this forum to no avail. After 7 years as an avid Opera user, it's the first time I have ever raised the issue of Opera falling behind. I don't like either firefox or Thunderbird but I use them simply because on my 512kb broadband Firefox + fasterfox makes a real difference.
Just look at the comments across a number of forums. Not all are credible but some (many) you cannot ignore

You are comparing a default Opera to a tweaked Firefox?! Not exactly an unbiased comparison, but hey, what do I know?
If you are already having problems with Opera being slow, why bother comparing it to other browsers anyway? Most people do not have this problem, so why do you bring up Firefox when the problem is obviously on your end?
Also if you look at the posts in this and other forums, not all but many, there is too much conformity to ignore.
I disagree. All Opera reviews from normal users I've seen keep saying how amazingly fast Opera 9 is compared to Firefox.

That doesn't really say anything about what most people experience. That you and a few others are having problems doesn't mean that everyone else has those problems.

Again, the comments I keep seeing is that Opera 9 is much faster than Firefox. I've read digg, Slashdot, Ars Technica, etc. Firefox fans are really impressed by Opera's speed, and some are switching, while others aren't (mostly due to extensions).

Thanks very much
Terry
Here is one way to do it:
. backup your old profile including mail - the path is under Help About Opera. Just copy the folders and keep them safe
. uninstall
. delete the profile
. install Opera 9
. Migrate/Copy/import what you need from your backed up profile/mail folder

I can - Opera is a lot - and I do mean a lot faster.
- During page loading, Opera requires quite a bit of CPU and tends to slow down the rest of the browser for a second. Noticeable when loading many pages in the background.
- Loading, displaying and scrolling very large pages with many relatively positioned elements (e.g. large forum threads displayed in one page) tends to be slower than it was in 8.
- The find / highlight-all-matches functionality works poorly on large pages, on extremely large pages this can even completely freeze the browser for half a minute on a modern machine.
Of these issues, the latter is one I think should have been fixed for 9.0 final, but overall I'm still very satisfied with Opera's performance and I'm sure they keep fixing performance issues as they've always done in the past.

I won't consider 512 MB RAM on a Pentium 4-M 2.00 GHz old equipment -- though at my end noticeably Opera 9 is less fast as Opera 8.54.

I'd consider myself normal and I assume your comment isn't meant as insult, right?
Maybe I am wrong, but I couldn't find any member's post on my.opera which claims that everybody has those problems regarding speed and hangs with Opera 9. Though, I understood that some people are having issues in respects of speed with 9 version compared to 8.54 version indeed.
I reported my experiences here: http://my.opera.com/community/forums/findpost.pl?id=1646540

Yeah, those articles, blogs and posts you're refering to are comparing FF with Opera 8.54, and yes 8.54 is faster than FF, this isn't the case with Opera 9 unfortunately.
Originally posted by Nilsen:

What do you know, Nilsen, may I ask you please ?
As far as I followed this thread, TerryWood spoke both clear & friendly language, he/ she spoke about personal experiences with Opera.
Why are you trying to make this member look dull or bad ? -- by your personal defaults is this fine arts of comunnication?
Nilsen try to play fair, please.
Hmm, or are you just on to provoke this thread to be closed soon, because it is critical about Opera 9, in my humble opinion (IMHO) this would be poor and I hope Opera ASA stays open to it's members experiences.
I've remained silent for a while.
When I saw your response I could not have put it better than If I had written your reply myself..
It is a shame that there is either bias or intolerance of personal views that just may be a tad critical of Opera which I have ALWAYS said is a good product.
I REMAIN INDEFATIGABLE and I am not going to change my views about Opera 9 and it's decreased page loading speed on my machine.

That's the way it is with all new versions. Some will claim that it's faster, and others will claim that it's slower.

No, you are wrong. I am referring to articles, blogs and posts about Opera 9.

If we want to help such people, the way is not to (only) tell them that they are wrong and Opera is quite fast; all it will achieve is a feeling of antagonism. We need to also acknowledge the fact that they are here because of a real problem, however localized it may be, and suggest fixes to their setup so that they can also see the same high-speed functionality that the rest of us observe. If I can only do the former and not the latter, I prefer to not respond at all.

Yes, and that's the point. He should focus on his own problem and leave it at that.

I did not get the sense that he was attacking Opera in any way. He has a genuine complaint which he voiced quite reasonably. That is what we ask people to do on these forums, and we need to respect that.

I can count/clock whole second intervals in different browsers.
I went to a page without banners or popups, just straight content, using Opera, a non-tweaked Firefox, SlimBrowser, NS7.2 and NS8. Fastest load on my machine, first look at the site, was Opera9 Then Firefox, then Slimbrowser, then NS7.2 and then NS8. NS8 lags far behind the others in almost every method of grabbing a page.
When reloading to force new fetch of cached images, over and over, speed varied back and forth between O9, SB and FF, with a slight edge going to O9, then FF, then SB
When loading page with cached images, same result. Again, NS7.2 behind and NS8 behind that.
Went to EBay and got the same results on first load and reload, with the difference that since the page is so heavy the time differentials are greater.
What I have here is Verizon Wireless (so the web speed is somewhat inconsistent from one moment to the next), WinXPPro on a custom-built with Intel MoBo, 512Mb RAM, and 3GHz P4. So, Obviously I can't speak to how Linux would handle these variables, nor how it would go on, say, a 600MHz machine or 64Mb RAM. My daughter (the IT Admin at her job) and her main IT vendor tested various pageloads between FF and Opera8 on cable at her job, and she claims FF edged out Opera.
There are many different things browsers are doing on different pages - from fetching, to rendering, to invoking different protocols and plugins to display different elements, etc. Some browsers will do each of these things differently than the next and some will do some better and other will do others better. In my everyday usage, I cannot tell a difference between FF and Opera overall as to speed. I use Opera because I'll be damned if I'm going to download/intall a bunch of extensions (which can have their own bugs) just to get the same functionality, or work in a browser w/out integrated email. I DO have my Opera set to ALWAYS check for new content, etc., while I let FF load from cache whenever it wants. One thing I find with Opera is that its habit of displaying cache on back-button by default, including typed-in form content, even in secure sites, is an enormous time-saver for me. I resubmit forms over and over all day with often slightly varying content, and cannot afford to wait for form pages to rebuild nor to re-fill form blanks. No other browser does this for me as consistently.
Everyone's setup and usage is different. So far I personally have never found a new version of Opera slower than one earlier. However, I do find the browser speed gap closing, and Mozilla and IE-based browsers no longer lagging behind, anything like they used to. (except I gotta say, NS8 really needs some work in that department)
Moral of the story:
Your mileage may vary.

Yes, and that's the point. He should focus on his own problem and leave it at that.
Let me establish some analogy.
There are IE-only websites that does not work well with Opera or Firefox. Those people who use the most popular web-browser won't experience problems visiting those websites. Only those who use Opera or Firefox will experience problem. But we don't require them to change the browser to IE. We don't tell them "it's your fault. use IE.". We require those IE-only websites to change its design. That is what we have to do.
I definitely did do a reinstallation of Opera, with a new profile, and took from the old profile only a few pieces (and I believe that was the critical piece that helped get the browser's performance back up). Also, I do want to note that I use the Comodo firewall, Vers., 2.3.5.62. (This is free software that has been rated very highly). I want to point out that the firewall software been recently upgraded. So query: does TerryWood (who uses Comodo) have the upgrade, which may make a difference.
Also, Commodo (once it's installed) (like Zone Alarm and other firewalls) asks a lot of questions about Opera (and certain parent software that makes use of Opera). If you answer a question wrong (say no, when you should have said yes, it's possible you could have a problem with Opera because of that answer.
One possibility (if you think that may be the problem) is to reinstall Comodo and answer all the questions again (making sure that you give Opera the necessary permissions. I have not, within the context of Comodo, needed to make a separate application rule for Opera, as the browser is operating quite well for me now. You can with Comodo define applications you consider trusted, and give them full internet rights, by opening the Application Window in Comodo, and clicking on Security. But I hesitate to do that with Opera, for fear some Trojan or other Spyware could hijack the browser. Anyway, there are Comodo bulletin boards at
http://forums.comodo.com/index.php?PHPSESSID=b026e51df471385d05db7dc3af9385cb&
where you can ask questions, about what can be done with Firewall settings to make sure they don't interfere with the browser. Also, the questions one may have may already have been answered.
I really thank neeraj Deshtukh for his considerate post here, about the tone appropriate to take in this type of thread. People should NOT feel defensive about expressing their concerns about Opera's performance (if they're having a problem), or be attacked by others for doing so. In terms of speed of a browser, all one has is one's own situation.

See http://www.wildcookie.com/grownups/help/ suggesting certain games might require java script, and java.
Also, supposedly java script can be for: "verifying the content of input data and displaying error messages."
http://courses.de.open.uoguelph.ca/d2l/orgTools/systemCheck/system_Check.asp
So is it worth it to change the browser default which enables java script.
Interestingly, Pandora,
http://www.pandora.com/
didn't work for me, until for that specific site I dis-enabled java script. Anyway, if the suggestion is made that there's a "speed" benefit to doing something, I think one ought to know what the downside is.
I mean, speed may be fine, but what's the trade-off?to understand differences (JS vs Java): search the inet with your favorite search engine for search terms "JavaScript resp Java", hmm or you may want to look up for those at wikipedia.org ...
Disabling Java is not critical for normal surfing, but disabling JS might well be ... all depends y'know.
Of course there's a down side by disabling JavaScript. Such as some menus in web sites won't work for instamce.
All I can say form my side is, disabling JS in Opera 9.xx makes surfing much faster, nearly as fast as my Opera 8.54 or FF2b2 both JS enabled.
But maybe I missunderstood your statements. Anyway enjoy yourself and browse safely.

Of course I accept that everyone is entitled to their opinion in this regard, nonetheless I would point out the following:
1. I have also timed page loading / rendering speeds between Firefox and Opera, as well as comparisons between IE and Opera, and using various Opera versions. Regarding Opera 9 vs. Firefox 1.5, I found that some pages would load faster in Firefox and others in Opera. Having said that, 9.01 and now the first 9.02 weekly seem to have made further improvements here. The truth is that each browser's loading and rendering method differs, which means that some sites will load quicker in some browsers than others It's unfortunate that some of your "favourite sites" may be those that load quicker in Firefox.
2. Opera's rendering engine and standards support are more complicated that Firefox's, for a number of reasons I've outlined in other posts. Depending on page features and browser specific coding, Opera may be necessarily slower on some pages, but could conversely offer a richer experience with (eg) CSS and page zooming.
3. I also use 512k broadband as well as a 2M connection. From my experience, in terms of perceived speed, there is little to tell Firefox and Opera apart in page loading and rendering speed terms on either connection.
4. Of course plenty of posters have vocalised these issues but that doesn't mean they're necessarily right, nor does it add much weight to the argument. There are plenty of other would-be posters who might say that Opera's faster than Firefox at page loading and rendering but see little point in saying so here on these forums. You might find them on mozilla forums, though.
Unless you can provide some kind of consistent and repeatable evidence of a problem it's not likely to cause much more than a debate here.

I guess I'd say that Opera is fast enough for me, that I don't want to risk partially rendered pages, where menus might not work, game sites, etc. As it is there are sites that are problems for Opera because they're not designed properly. It's frustrating browsing at some of those sites, that render without a problem with Firefox or IE. I don't want to increase that problem of poorly rendered pages. All I was suggesting is that if you're going to mention that disenabling java script will increase speed (which is interesting, and which I didn't know), it would help to point out what the downsides might be (because most of us are not technical/computer gurus). The default was put there for a purpose. In any event, thanks for the suggestion about java script, as it is an interesting thought. You get X, but you lose Y. So the user has to decide: which is more important.
regarding
3) at my side both 9.01 and 9.02 are slower than 8.54. Firefox 2b2 resp BonEcho 2 nightlies are faster than Opera 9, to my opinion they're like 8.54 in regards of speed here.
4) ... hmm ... yes (!) -- so what? Of course both browsers have their advantages.
For me personally an important thing is speed and fast page rendering. All this CSS and JS caboodle i'm sick of meanwhile.
[Example: compare 8.54's CSS style sheets, like about:Opera, plug-ins or history etc pp with 9.xx , I mean who needs this really, 9.xx versions style sheets are hard to read here unless you zoom to min 120%. Another example: JS1.6 in 8.54 works fine for most web sites out there but JS1.7 in Opera 9.xx obviously not (but BonEcho 2 seems to know how to handle JS1.7}?
Readability of news sites, i.e. such like news.bcc.co.uk, why can't Opera handle this site like FF, the Opera-zoomm-page is a mess compared to FF2 'enlarge text size'.
Anyhow -- Each to its own.

ps as I said in previous posts I have Comodo Personal Firewall and Avast A/V Process Guard and others along with GESWALL
I know this is an old post, but I have problems almost identical to the ones mentioned above. A lot of pages stop completely at the last two or three items and the browser sits for several seconds before it will proceed. The browser completely stops responding when this happens. I do have one page (Newzbin.com) that I had to disable javascript completely before I could use Opera to browse the site. It would actually load and display the page, but I couldn't scroll for several seconds. I am running Windows XP SP2, AMD 950 with 512 of ram.
What do you mean with "I have problems almost identical to the ones mentioned above"

I.e. like DynaBMan has almost the same avatar like TreeGo ?

What does my avatar have to do with this thread?
As for IE, I stopped using it years ago.
