Are you also following the 'Excessive NFS operations' thread? There's
some interesting information there about buggy kernels and apps.

This has very little to do with the number of clients or directories,
except that in general terms more users = more work.

You might want to set yourself up with a performance monitoring system
like Munin to give you more extensive data, as well.
If you get that far, you'll find the iostat plugin to be a bit lacking

Hi,
We have a storage server (HP DL360G5 + MSA20 (12 disks in RAID 6) on a
SmartArray6400).
10 directories are exported through nfs to 10 clients
(rsize=32768,wsize=32768,soft,intr,nosuid,proto=udp,vers=3).
The server is apparently not doing much but... we have very high waiting IOs.
