83819 - CPU 100%, Mozilla stalling, when viewing VCL Filtration

Status: RESOLVED WORKSFORME

(Core :: Layout, defect)

Description

[Kelly Price]

I'm seeing alot of related bugs (#78462, #61684, #68997) to this one.  This one
is when you pull it, Mozilla (Build 2001060115 on Linux) stalls, no throbber, no
responce, for about a minute before it redraws and continues loading in
thumbnails and full pages.

Repeatable?  Definetly.  Always happens.  Just load the page.
No stalling is expected.

This is worksforme on win2k build 20010603.. (CVS opt), Athlon 1.33Ghz, 512MB 
RAM.

Reporter: 
This is maybe a performance problem.Can you poste your System Details (CPU and 
RAM) ?

2001060115 on a Linux 2.4.5 (Slackware-current) system; AMD K6-2 on 160 Megs of
ram.  Xfree 4.0.3 with a VooDoo 3 properly configed in kernel and in XFree, and
Gnome 1.4. I had the same problem with previous builds.

There are some issues with Linux's memory handling that are slated to be
resolved in 2.4.6 (it caches too much swap), but I'm not sure if it's related or
not, since swap is unaffected when I load the URL above.  I've got a memory and
CPU meter on a dock on the side, and the swap indicator doesn't move.

wfm using build 062906.
running SuSE 7.2, mobile pentium 850Mhz, 128MB RAM,
system load according to 'top' for Mozilla-instances:
CPU: 3,5%
MEM: 25%

Kelly, could you please retest it with a newer build?

Still 100% durring load, but it rebuild the page too, on Linux build 2001063006

Comment 5

[Con Kolivas]

WFM on linux build 2001070116, cpu load 2.5%, using PIII/733 256Mb Ram, with
cable connection. Perhaps related to a lower bandwidth connection? It stalls
slightly till the whole page can be viewed (minus the images).

Comment 6

[Kelly Price]

his bug seems to be related with bug 92611, since the CPU goes 100% and
refreshes.  Maybe dependant on this bug?

Comment 7

[Keyser Sose]

Marking NEW.

Comment 8

[Tom Mraz]

Resolving as WFM with Linux 2001092021 build. Reporter please verify.

Comment 9

[Kelly Price]

Negative.  I'm still getting this, even after upgrading to 256 megs of RAM on
this Linux box on build 20010921.

Could this be a layout problem, since the page uses a ton of tables?

dbaron, reassigning to you, since it involves performance issues. Bounce it back 
if you don't want it.

Comment 11

[ChrisB]

WFM using build 111521 running on SuSE 7.3

Kelly, could you please retest?

Comment 12

[Kelly Price]

Retested on 2001111706.  It's no longer forcing a refresh, and the CPU's much
better now.  It however likes to lanquish on the page.  Is Mozilla
machine-gunning image requests out?

Comment 13

[Kelly Price]

I've just upgraded to Mozilla 1.1 (Build 20020826) and I no longer have any
stalling.  It still goes 100%, but it goes straight through.  Someone add some
pacing to it?  Oh well, I'm resolving this bug.

Since nothing was done to fix it, it should be worksforme, not fixed.

->worksforme.  See previous comment.
