Unless someone fixes the problem pretty soon our strategy is going to move away from filers everywhere to just a couple of filers at the centre of the network. Anyone else think it would be worth netapp
Heh, that smacks of shooting the messenger.
It silly to blame the server, when it's clearly the client's fault.

I quite agree its not netapps fault in any way whatsoever that linux' nfs client doesn not cope well with parallel workloads. However speaking for myself alone netapp will sell us 10* more filers if the performance of linux improves. Now even if I only buy 1 filer a year if things don't improve and that I pay $100k for a filer then thats $1m that I haven't spent with netapp. Say there are a just dozen more customers in my position then there is a probably $12m return on an investment of a bit of engineering resource. 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!!

Not exactly what you have in mind, but does show there is interest in supporting Linux...
