Build ID: 2002-06-13-08. Windows 2000. 850 MHZ PIII. Given URL causes Mozilla to hang for several minutes, sucking all cpu. The page is quite big (c:a 1 MB), but renders in a few seconds both with IE 5.5 and Opera 6.0.
Keywords: hang
I should also mention that I killed the Mozilla process after three minutes.
Same here with Win98 2002062308.
No hang with 2002062008 Win2k It just takes ridiculously long to render. UI was unresponsive for approx 1 minute and then the page and mozilla was fine. PIII-800
WFM using trunk build 2002062404 - WinXP. I also have a DSL line. Long time maybe related to server or connexion used by user ?
Well, I've got a 1 Mb/s lease line that's extremely reliable. My ping time to the server is round 20 ms (we're both in Sweden). But I can confirm the observation of WD in comment # 3: If I wait long enough (several minutes) the page does indeed render. Another observation: The rendering seems to happen in several "chunks"; now and then the scrollbar shrinks and jumps a bit. I'm changing the summary as to better reflect the issue. Also changing component to something hopefully better.

Confirming 2002061712 Win2000
The big culprit is nsDocLoaderImpl::GetRequestInfo (which already has bugs on it about this). The rest of pageload is spent constructing frames, doing image loads, etc.
Keywords: mozilla1.2, perf
Confirming with the latest branch build: 2002-08-01-08 on WIN2K. Takes long time to load the given URL and hangs the browser.
Status: UNCONFIRMED → NEW
Ever confirmed: true
Priority: -- → P2
Target Milestone: --- → Future
A possible reason for this page taking so long to render is that it contains hundreds of <font> tags, but just a few </font> tags.
