So it's something like a 10-15% improvement.

IMAP benchmarking is really hard to do well. :)

Note that imaptest mainly tests CPU usage, not disk I/O because most of the files will stay in OS cache. The real world performance should be better than what imaptest shows.

mmap_disable: yes

If indexes are local, there's no need to disable mmap.

mail_nfs_storage: yes

mail_nfs_storage=yes makes Dovecot slightly slower compared to v1.0 (but fixes problems with multiple NFS client machines).
