Do you have RandR and DRI enabled?Do you have RandR and DRI enabled?Posted Jun 19, 2008 19:03 UTC (Thu) by khim (subscriber, #9252)In reply to: fsync, maybe by asamardzic Parent article: Over 8,000,000 Mozilla Firefox 3 Downloads in 24 Hours (MozillaZine)
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.

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...)
