I've attached a slightly cropped rrd graph of NFS read bytes/sec on 6 mail netapps from one of our datacenters. See if you can spot where we started moving IMAP to dovecot over the course of about a month :)
While we're sharing graphs, I've got one you might like - dovecot on NFS mounted with noac vs attribute caching enabled. noac fixes some distributed locking issues quite well, but absolutely trashes the servers.
