I remember people complaining about GFS2 (and other cluster filesystems) having bad performance. But in any case whatever you use, be sure to use also http://wiki2.dovecot.org/Director Even if it's not strictly needed, it improves the performance with GFS2.
Object storages also scale nicely (e.g. Scality). For best performance with them you'd need Dovecot object storage plugin (not open source).
