Very POOR FireFox 14.0.1 Performance

The other interesting thing to note is that people forget to share the bug number!

I have to confess, I haven't filed a bug report myself. It's easier just to move from Firefox to Chromium.

I have noticed the performance difference between Firefox and Chromium as well, now with Firefox 15.0.1. Firefox seems to require much more from X when scrolling, for example. On the other hand, Firefox respects better window manager's (say xfwm4) settings concerning e.g. raising a window when clicking inside it.

I use even older, less powerfull hardware: AMD Ahtlon XP without SSE2, NVIDIA Corporation NV17 [GeForce4 MX 420] (rev a3) graphics, so the browser ui responsiveness is important.

I am using Firefox 15 on an old Compaq laptop with intel gfx and it feels smoother and faster than Google Chrome on the same machine... Maybe it's down to gfx drivers and their support, or it could be the fact that I disable web caching and it's all in memory...

I also suspect there is something wrong in X. At least in ubuntu 11.04 on the same hardware even running grsync went unusually slow because X was using so much CPU. I guess displaying progress bar was not implemented optimally in X.
