There are actually two ZFS raid1 but in the same zpool, and the SSD in local, not in the ZFS dtorage. The latency was because I tried to use a ZFS for datasore of a vmware undres NFS, and NFS under vmware is always synchronous. I improved 10 times the performance under iSCSI

So, you need customizable userdb lookup without ldap or sql. You can try too use checkpassword as userdb and then, in the script - parse quota-file, make pam lookup and return userdb_quota* values for specific user. More on http://wiki2.dovecot.org/AuthDatabase/CheckPassword . I don't have experience with this authdatabase method, but seems that it suitable for you. But in general - it's better to prevent editing maildirsize file from 2 instances.
