Have a mid-2011 Mac mini server (2.0GHz i7, 16GB ram, dual 750GB internal SATA) and having my iTunes library (25257 items, 155.85GB) sitting on the zfs store means there's a 1-2 second delay every time I skip a song
ZFS looks like this:

errors: No known data errors
If i put the same library on an HFS+ disk via firewire800 I get no such lag when switching tracks.
Thoughts/ideas/diagnostics to run?
