The Musings of Chris Samuel

I’m a bit behind at the moment, but this is something worth a mention.

Ricardo Correia’s port of Sun’s ZFS (which I’ve been playing with for a while) has finally reached its first beta release!

He’s made some useful performance improvements recently as well as tidying up some of the memory handling and fixing various bugs, including that bug from the upstream that yours truly got bitten by.

Here’s an updated Bonnie++ run for comparison.

Compared to previous results the write speed has improved, but the read speed seems to have dropped off a bit. Still, it’s early days yet.
