268683 - Extremely slow scrolling and general poor performance

Status: RESOLVED DUPLICATE of bug 201307

(Firefox :: General, defect)

Description

[Asher]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

At http://www.bungie.net/stats/Default.aspx, Firefox performance is terrible. 
Scrolling is incredibly slow and jerky with and without autoscrolling and
smoothscrolling on a Pentium 4 3.2GHz.  Task Manager in Win2K shows CPU usage
never peaking above 49%, yet the performance remains terrible.

Further, it's not just scrolling.  Right clicking produces a noticable delay
before the menu loads.  

As far as I can tell this page does not have Flash or a fixed background, which
are other slow scrolling bugs I've found.

Reproducible: Always

For what it's worth, similar issues can be seen with www.warp2search.net. That
site has always scrolled slowly for me.

I suppose it would help if I were to provide my system info as well. I've got an
AMD Barton 2500+ @ 2.26GHz with 1GB PC3200 RAM. I'm on XPSP2.

I tried your site in FF 1.0 and it loaded horribly slow at 100% CPU on my XP Pro
SP2 P4-1.7GHz 1GB RAM 3GB free HDD system. However, I tried loading the same
site using FF 0.9.2 and it loaded nice and quick!

I just installed FF 1.0 yesterday and notice something terribly wrong with its
performance on many sites, like winamp.com. Also notice all the various forum
posts about this bug. Something's definitely up, and I'm going back to 0.9.2
till I hear it's fixed.
