Someone jprof this. Please use Browser-General until you can prove JS is to blame. /be
With a current Linux build I see us taking about 10-15% of CPU (on a P3-733). Mostly animating gifs (hence painting) and doing some JS off a timeout. So in short, I can't reproduce this bug.
This is another example where even Firefox1.0PR goes down and utilises 100% CPU (but not crashing, visiting another URL solves the issue): http://free.grisoft.com/freeweb.php It really seems to be JS, I suspect the ticker to be the source of the performance-hole. Tried on Firefox 1.0 PR/WindowsXP and on Firefox 0.9.3/BeOS on a different system.
> This is another example where even Firefox1.0PR goes down The rendering engine in Firefox1.0PR is 6 months old. In particular, it's about 3 months older than the rendering engine I was using in comment 5. Please do test a current trunk build; there's been a lot of work in the last 6 months on DHTML performance. If you still see the problem, please file a separate bug on it (and cc me).
http://free.grisoft.com/freeweb.php and http://www.ag.ru/?gallery?12026?76206 both WFM - no 100% cpu for FF 1.0.4 or for Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9a1) Gecko/20060625 SeaMonkey/1.5a Please reopen if you still see the problem on a current version of the suite.
