Sort of.  Some fancy parts of X like file-manager/exporer applications tend to 
call fstat() a lot, but it's probably tunable, and if you enable NFS attribute 
caching that will help a lot.  "ls /afs", if available, is a wonderful test of 
whether a program/file-manager is being polite.

Anyway, "top -mio" is likely to be informative.
