If I was netapp right now I'd be trying to work out who to assign to a linux performance project :-)
Our company would really appreciate that. ;-)
We've made lots of testing today. We didn't see anything unusual in the netapps filers, but our Linux servers got all stressed out when we simulated like 150 simultaneous POP3 processes working (moving random files from spool/mail to pop, and reading slowly from it).
We are *not* positivily sure yet, but we believe it is in fact a problem with our current Linux/Kernel version who can't handle correctly our NFS demand.
We'll be trying next week the new 2.2.16 kernel with patches from http://nfs.sourceforge.net/ to see if things gets better.
Ariovaldo, Raquel and Alexandre from Brazil's NetApp joined our tests today. They're all very good people.
As we do our tests next week, I'll keep this list updated with our success/failures. (success only hopefully... ;-)))
Thanks all who replied!!
