Do you use one or more Dovecot servers?
Two dovecot servers with round-robin pf balancing and NetApp NFS storage over gigabit ethernet
That pretty much explains it then. See http://wiki.dovecot.org/NFS
Thanks! It seems that my problem is fixed in v1.1 with mail_nfs_storage = yes and mail_nfs_index = yes, am I right ?
Yep. Although it still would work faster if you could do per-user (or at least per-IP) redirecting instead of randomly directing the connections.
IIRC in my stress tests accessing a mailbox from only one server was 2-5 times faster than if it was accessed from two servers simultaneously.
