I think I've cracked it!
carolina# (43) zfs create -o compress=off rpool/test
carolina# (48) dd if=/dev/zero of=/rpool/test/tt bs=512k count=10000
5242880000 bytes transferred in 13.199665 secs (397197954 bytes/sec)
Mirrored rpool on 15K SAS disks. Previously I was hitting 20MB/s maximum.
No more errors in the controller firmware log either.
I'll test properly over the next few days and clean up the diffs, but it
looks good and the changes should only affect the non-RAID code.
