Be careful to no do any synchronous writes under ZFS. Every sync write can take up to 3 seconds of latency (under freebsd, I didnt test ZFS in linux). Im using it in a 3k user environment and works great with a 4TB raid 10, and dovecot cache files in a SSD disk.
From what I've heard you should not use hardware based RAID (ie, RAID10) setups with ZFS, you should let ZFS handle it.
Maybe that is the source of your latency issues?
