poor X/gnome performance on a Dell Poweredge 2550

[shane stixrud org]

I am seeing pretty poor Xwindows performance on our Dell Poweredge 2550 
server running 3.0B1 Advance Server.  The worst test case I have found is 
opening up gnome file browser and displaying a directory with a lot of 
files /dev works great.  Performance gets so bad that the mouse cursor 
will jerk and then freeze for a few seconds.

Anyone else seeing this issue?

Shane.
