Your problem is most likely Flash/Javascript based (I'm basing my

No matter what OS you have, if a website's slow (and it's not
because you don't have OpenGL support in your X-server), slowness will
remain constant. It's just the way unfortunately that browsers are designed.

Not really when the slowness does not exist with 6.X.

I have experienced certain websites causing firefox to slow down considerably. When I mouse over firefox the mouse begins to jerk as well but when I move back away from firefox it seems fine again. I suspected it was an x/firefox bug.

Actually I double-checked this case with dailytech.com. It seems to be spending all of the cpu time in user-space in xwindows. So it seems that it is the new xwindows that has the problem. If you watch the 'TIME' field of top you can see that very little cpu time is attributed to firefox and quite a lot to X windows. So the windowing system is too busy to redraw mouse events even if we are scheduling it well.

Although I also sometimes observe mysql hanging for a period of a half second or so while running sysbench. I wonder if we don't have a threading library bug? I know I observed this prior to the thread_lock work so hopefully I didn't break it.
