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... -- john r pierce N 37, W 122 santa cruz ca mid-left coast
