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...
