fsync, maybefsync, maybePosted Jun 19, 2008 17:39 UTC (Thu) by asamardzic (guest, #27161)In reply to: fsync, maybe by elanthis Parent article: Over 8,000,000 Mozilla Firefox 3 Downloads in 24 Hours (MozillaZine)
There is not much of the disk access throughout the freeze, but on the other side I noticed the problem re-appears if I work for some time with other tabs, and then get back to the tab where the image is loaded, so indeed it's probably something with the image rendering (BTW, the color management is off)... In any case: thanks for all suggestions, and the pointer to the proper place to ask for support - am trying my luck there, apologies once again for asking the question here.

Do you have RandR and DRI enabled? Posted Jun 19, 2008 19:03 UTC (Thu) by khim (subscriber, #9252) [Link] Recently found that if you enable OpenGL support in some versions of binary ATI drivers it disables DRI and RandR and Firefox 3 becomes SUPERslow. Firefox 2 is not affected.
Do you have RandR and DRI enabled? Posted Jun 19, 2008 19:19 UTC (Thu) by rvfh (subscriber, #31018) [Link] This is indeed a problem that exists with nVidia cards too. See this: https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bu...
Do you have RandR and DRI enabled? Posted Jun 19, 2008 21:58 UTC (Thu) by nix (subscriber, #2304) [Link] Why would Firefox care about DRI? It's not doing 3D stuff, is it?
Do you have RandR and DRI enabled? Posted Jun 20, 2008 9:47 UTC (Fri) by jamesh (subscriber, #1159) [Link] I'd guess that the problem is poor performance from the Render extension. It is possible that disabling DRI also disables the acceleration of that extension, leading to the poor performance.
Do you have RandR and DRI enabled? Posted Jun 22, 2008 22:31 UTC (Sun) by nix (subscriber, #2304) [Link] I think only EXA accelerates Render to any extent, so if EXA is being disabled (falling back to XAA) you *might* see a slowdown. (However, on my distinctly aged Athlon desktop with a distinctly aged Radeon video card, I see no performance problems with the render extension at all. However this might be because, my failing memory tells me, the Radeon 9250 et al are one of the few cards to have XAA-accelerated Render...)
