Pursuing invetigations, i have discovered that for people having workstations whose home directories are on a NFS server, and who run Gnome or KDE, there is a program which has horrible NFS behavior, it is gam_server from gamin, which detects alterations on your .kde for example. On my machine running nfsstat -c -w 1 i see 4000 requests/s due to that. If i displace it (*) and kill it, this drops to 80 requests/s and KDE works exactly as well, including discovering new files. I think it is not necessary to comment on the performance penalty if a number of stations send 4000r/s to a server, it will soon be killed. (*) it restarts itself automatically so it is necessary to displace or rename it before killing. -- Michel TALON
