the last post in the thread:

I didn't find similar problems with neither Konqeror nor Dolphin.  After further examinatioin it looks like it's linked with X.Org (X.Org X Server 1.6.4, X Protocol Version 11, Revision 0). After checking with top I noticed that Xorg jumps up it's CPU usage remarkedly (from a couple of per cent to something around the 60 per cent mark) whenever I change dirextory in Krusader. Unfortunately I'm not knowlegdable enough to determine whether that makes it a Krusader or X.Org problem.  Anyway thanks for taking the time to respond.  KJ

After 9.04 to 9.10 upgrade, I've the same issue on all application: Xorg take up to 90% of the CPU. 
For me the issue came from /boot/grub/menu.lst which I didn't update during upgrade. 
That means I continued to run old kernel. 
After menu.lst update with last kernel launch, everything run fast.
