My favourite stress tester is repeated kernel compiles, plus the same
again in a chroot'ed mount-point. This mount-point is mounted via NFS
from the same box.

It's more of a hardware test than anything else (although I suppose it
uses the fs code a fair bit :-), so you'd obviously want to add some big
ftp sessions in the background, fire up X/netscrape, and perhaps play a
bit of quake (with about 1 frame/min by this stage :).

Anyone else have useful sadistic tricks?
