Had extremely positive experiences with it about eight years ago. I used to produce some gcc packages for FreeBSD, and that meant having about four gcc builds running in the background at any given time. I'd regularly do this and *still* have glitch-free audio whilst the builds were going on. This was on an early Core i7 machine with a three-disk zraid array (two disks striped plus parity). I think part of the reason it seems so fast is that the built-in compression seems to reduce traffic on the SATA bus quite considerably. I have no experience running ZFS on Linux though. I've resigned myself to running ext4 there. Still running ZFS on FreeBSD to handle file serving and backups though. -- Mark Raynsford | http://www.io7m.com
