Hello,

a mailserver of us is storing the messages on another server with NFS 
through TCP. A lot of concurrent deliveries occur, but I can only see 
about 8 nfs processes on the storage server. The mailserver which 
accesses the storage often has very high I/O waits (>400 seconds), 
because the NFS server doesn't respond in time. How can I increase the 
NFS-processes on the storage server? Right NFS is a real bottleneck and 
a lot of mails are delivered with a delay of 1-3 hours.

Regards
Marten
