Hi.
As far as I know UFS is faster than ZFS on FreeBSD 9.0.
Some users reported stability problem with ZFS on AMD64 and maybe UFS is
better choice.
Best regards

Hello,
Under FreeBSD 9, what filesystem should I use for PostgreSQL? (Dell
PowerEdge 2900, 24G mem, 10x2T SATA2 disk, Intel RAID controller.)
* ZFS is journaled, and it is more independent of the hardware. So
if the computer goes wrong, I can move the zfs array to a
different server.
* UFS is not journaled. Also I have to rely on the RAID card to
build the RAID array. If there is a hw problem with it, then I
won't be able to recover the data easily.
I wonder if UFS has better performance or not. Or can you suggest
another fs? Just of the PGDATA directory.
Thanks,
Laszlo
