Appalling desktop performance in F8

["Alastair Neil" <ajneil@xxxxxxxxx>]

Has anyone else experienced terrible desktop performance with F8.  Under F7 on the same hardware I never had any significant problems, now it appears several times a day my desktop locks up (or appears to), mouse movement seems unaffected yet windows are unresponsive and I cannot move of select any windows or panel objects, even the ctrl-alt-f virtual terminal sequence seems to be ignored.  The media player continues happily playing audio. CPU load seems pretty high during these lockups and pulseaudio appears to be consuming much of it.  Usually if I am patient the system unlocks, however often I resort to extreme measures.

Typically I used to have under F7 firefox, thunderbird several gnome terminals, rhythmbox and occasionally openoffice open.  I have now resorted to epiphany, thunderbird and quodlibet ( I cannot use evolution these days, I have become addicted to the grouped by sort G  feature). 

The system itself is a P4 2.8 GHZ Dell optiplex 270 with 2 Gbytes of memory and an older nvidia card with two 19 inch monitors. I am using the xorg-x11-drv-nvidia-96xx drivers and my home directory is mounted via NFSv3 over gigabit ethernet.

I'd appreciate knowing if anyone else has had similar problems before I roll back to F7.  It is possible that I am having hardware problems, so the F7 roll back may not help.

Regards, Alastair Neil
