Well, the UFS results are miserable, but the ZFS results aren't good - I'd
expect between 250-350MB/s from a 6-disk RAID5 with read() blocksize from
8kb to 32kb.

Most of my ZFS experiments have been with RAID10, but there were some
massive improvements to seq I/O with the fixes I mentioned - I'd expect that
this shows that they aren't in snv44.
