We used to have RHEL4 talking NFS to bluearc (instead of netapp).
Switching to solaris 10 improved performance about 10 fold.
The app was postgres though, not dovecot.

What operating system are you using? Performance over NFS is
tremendously different. And each OS can be tweaked differently.
You should try noatime (noxattr on solaris) regardless.
RHEL4u3 64-bit. I will try noatime.
Thanks

We are seeing some poor performance recently that is focused around
users with large mailboxes (100,000 message /INBOX, 80,000 message
subfolders, etc).
The performance problem manifests as very high system% utilization -
basically iowait for NFS.
There are two imap servers with plenty of horsep
