Following up on this, I've taken the opportunity this weekend to
migrate the N40L from Btrfs to ZFS-FUSE in a mirrored configuration
(two mirrors of two disks each). Taking the parity calculations out of
the loop makes for a huge performance difference. It's 5-10 times
faster than RAID-Z and close to Btrfs performance for reads. Writes are
still slower than Btrfs but that's FUSE's fault. I know I can get at
least a twofold write performance boost with a native ZFS driver so the
next step will be to see what I can do with Debian kFreeBSD.
