Confirming... on a P4 2.8GHz cpu, trying 'firefox' at the command prompt results in a ~20-second wait before the window renders on screen. Then it takes another 30-40 seconds to display the default readme page. Doing *anything* with Firefox (other than just looking at it :-) causes CPU to spike to 100%... including just typing in a form field! Tried the MOZ_DISABLE_PANGO=1 setting documented elsewhere in bugzilla, makes no difference (seems even slower, actually). Worth noting, though, is that firefox aside, the X binary seems to take up a LOT of cpu time for... nothing. A scrolling gnome-terminal spikes CPU to 100% for as long as it's scrolling. And that's on an AGP 4x ATI Rage 128, which should have more than enough 2D framebuffer bandwidth to scroll its silly head off without making the CPU even break a sweat. Bottom line: *something* is making X take a *lot* of CPU cycles, no matter what app. Attempting private build from source to see if problem is FF1.0.4 or the RPM package. This is a 'me too'. I've got an AMD Athlon(tm) XP 2700+ with 1GB RAM, and firefox 1.06 is also painful to use with every pageload pegging the CPU for 1 or more seconds. It's probably the javescript ticker that is causing this. Like on this page: http://www.php-tools.net/site.php Add-block can do wonders on these pages :) I'm afraid it's not javascript-related. Sitting on "about:blank" and merely moving the mouse pointer over the window causes the CPU to peg at 100% until I move the mouse pointer away. I'm not certain the problem is Firefox-related, as everything else on my FC4 system seems to be about 50% as fast as it was under FC3. I am seeing similar problems with firefox-1.0.7-1.1.fc4 trying to access http://www.delfi.ee/. that was fixed definitely fixed in firefox 1.5.x.x |
