Did you do any tuning to ZFS? There are many tweaks to it, like
putting a cache disk in front of it, or moving the logs to SSD and
such. I haven't run any produciton DBs on ZFS yet, but it sure is
tempting. The speed penalty for the features it gives you (snapshots,
robust against power fails, etc.) is worth the tradeoff.
No, I didn't do that kind of tuning - agreed, it'd improve the
performance. But then putting an SSD in the mix and storing journals on
it would have improved the performance of XFS and ext4 as well..
I'll re-run the tests again in the future, no doubt, and hopefully I'll
have a spare SSD by then. Also maybe I'll have learnt more about ZFS;
I'm a bit of a noob at the moment.
I agree that ZFS does seem to offer some rather nice features though!
I'm tempted to start using it on my personal server now; although I'll
be leaving it for some time before considering using it in production at
work.
Cheers,
Toby
