ZFS is very memory intensive on larger file systems. I believe they
recommend on the order of 1GB ram per terabyte of storage for decent
performance.
Personally, I would only run ZFS for any sort of production application
on a Solaris 10/11 system where its natively supported, and then only
with a support contract from Oracle.
When its good, its very good, when its bad, its reformat and restore
from backup time...
