[10.54 b3390] Huge pages lock up Opera

[10.54 b3390] Huge pages lock up Opera

Hi,
I have been seeing some huge pages recently which lock up Opera for up to a minute. What's more annoying, this is not only while loading and rendering, but also later e.g. when returning to these tabs.

Examples:
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/ChangeLog?id=0.8.0.998
http://cvs.fedoraproject.org/viewvc/devel/

I don't know whether it's the size, or the pages consist of large tables.

"Lock up" means Opera is totally unresponsive for some time, like for tens of seconds.

Is anyone seeing the same thing?

Opera 10.54 build 3390 on Windows 7 Enterprise (64 bit).

Totally yes, and it's frustrating as hell. Visiting any big page slows my comp down to a crawl, and I'd like to think I have a decent comp.
I'm on 3394, Win XP 32-bit btw.
EDIT: Just to clarify, didn't test either of those 2 links, cos didn't want to experience the slow crawl, but tested today and both are about ok.
http://dev.w3.org/html5/spec/Overview.html on the other hand, does slow Opera down a LOT for me.

Hmm. Opera doesn't lock up, or even noticeably slow down for me on either page on build 3394, Windows 7 Pro (64 bit).

What sort of hardware do you have? I have a dual-core 2.1 GHz processor, 3GB RAM, and a GeForce 9400M G.

On my quad core AMD Phenom with Win 7 x86 the first url isn't a problem. The second one had the CPU usage working between 15-20% for several seconds. That is 60-80% of a single core.

Windows says "Intel(R) Core(TM)2 Duo CPU T9600 @2.80GHz 2.80GHz", 4 GB RAM. A really nice and sufficiently fast laptop. (And the HDD is fast too, it's an Intel SSD.)

The second link locks Opera for around 70 seconds, Opera shows CPU at ~49% in SysInternals Process Explorer.

more strange - try this:
http://gutenberg.spiegel.de (will proobably hang opera)
is just fine as long as one dont scroll O_o - it crashes opera otherwise

The Gutenberg link works fine here.

Version 10.54 Internal
Build 6340
Platform Linux
System x86_64, 2.6.33-zen2

Also, I don't see much of a slowdown in the NetworkManager link (in the OP). It takes time (~10s) for it to render the whole page, but after that opera is fast. No slowdown also on switching tabs. The second link is really slow to respond, so I abandoned testing it.

confirmed and reported DSK-300462 locks opera tight if you scroll

cheers!!

well i am still on 10.53 - so if it works fine on 10.54 - must have been fixed already^^

Gutenberg link worked for me on 10.54 and 10.60, even with scrolling.

10.60 handles those big pages much better, still some minor hangs while loading, but only for a second or two.

Sorry Guys the Gutenbert link still locks me up and pegs my cpu at 100% usage . I have a Older Machine 1.8 gig processor 2 gig's of ram and a 250 mb video card.still that should not happen . I went to the same site using Internet Exploder 9 with no Problem.

I tried once more, now with Opera 10.60 b3403. No other tabs or pages open except for this forum entry.

Both my original links and the w3.org link from the subsequent poster lock up Opera for 45 to 70 seconds. I wonder why some people aren't seeing anything peculiar at all.

I might just file a bug?

Absolutely no problem with the Gutenberg site here (XP SP3). But if you want a weird behaviour then go to FixYa
http://www.fixya.com/Unanswered.aspx
click on a few links - go from one question to another and the try to go back - Opera will simply refuse to go back.

It must be a bug in the alpha build. I work at fixya part time and never had a problem before. Now I do ...

Actually i've always had problems at fixya - none of the reply box options ever worked - but now it's got to ridiculous levels.

The Gutenberg site gives me no problems on 10.54. It loads in 8.8 seconds (a bit slow but only slightly so) and I can scroll there with no problems.

http://dev.w3.org/html5/spec/Overview.html took 88.8 seconds to fully load. I'm on XP Pro SP2 computer. Even with the slow loading, I could leave that tab and go to others and come back to see if it had finished loading.


http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/ChangeLog?id=0.8.0.998 took 15.75 seconds to load. Not fast but not bad.

http://cvs.fedoraproject.org/viewvc/devel/ took 16.431 seconds to load. Again, not fast, but ok.

This computer is over 4 years old with a 3.8GhZ Pentium 4 processor with hyperthreading (old Dell XPS gaming machine) with 2GB RAM, nvidia board. Loading any of those large sites, both processors are used equally and at 100% for a couple of seconds but mostly much lower CPU usage while loading. I even loaded a second instance of the fedora one while the first was loading and didn't see a slow down. The only problem one for me is the dev.3org one. I had loaded individual links from that page yesterday after I installed 10.54 and the links loaded very fast. 10.54 is much faster than 10.53. It loads many pages in ONE SECOND. It's so fast. I can't believe it.

In 10.70 b3488 (I know, I'm two builds behind), this is still driving me nuts.

Since the second link I had originally posted has moved, let me give you a new location:
http://pkgs.fedoraproject.org/gitweb/
This locks Opera up and "never" returns (unlike other large tabled pages), at least not for 3 or 5 minutes or so. At the same time, Opera's memory footprint constantly (but slowly) increases. Perhaps Opera is still processing the page.

By the way, IE8 takes about 20 seconds to load the page (I can jump to its end) and another 10 seconds to complete rendering. It's a tough page.

10.70 b3488, Windows 7 Enterprise 64bit

Locks up? Well, not the latest Windows version (9036). It did take about a minute to process such a large table, but I started typing this while it was still working. And I only have a 1 GB system with a 1.60 GHz Atom processor running XP SP3.

Yes, locks up. That means while (seemingly) processing that tab, at some point I get the egg timer (or whatever you call that under Windows 7) and the Opera window grays out. The other Opera windows display ungrayed until I try to do some activity in them. (Win7 probably doesn't notice that the window is unresponsive until the user tries to do something.)

On other pages which slow Opera down, Opera is responsive, but only occasionally, meaning you can't scroll smoothly anymore (only in intervals of a few seconds).

My processor specs are above, and they're really not bad.

gibson

P.S.: This is driving me mad!

I really don't see the point of reporting problems with out-dated builds.

I see no problem with the latest build of 10.70 (9036). The page takes a couple of minutes to load, about the same as IE9, which behaves in much the same way. In either browser, I can scroll straight down to the bottom while the page continues to load and the scroll thumb moves back up as the page continues to load.

Since it's been there for months, I didn't see a specific reason for.... Oh well, I give in, just for your pleasure, I updated to 10.70 b9036. Same phenomenon.

No relation to other tabs' memory usage, because if I start Opera only with that link (and this forum thread), it also locks up. Memory usage remains low but creaps up every so slightly.

Since nobody else here is seeing it, I reported a bug, DSK-312551.

If you have any hints regarding what else to try, please do go ahead.

Just found the Spiegel-Gutenberg-Problem here and want to add that i reported that problem a few days ago. So my bug-report could be a duplicate.
