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,
