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.
