I didn't look too closely at the details, but I don't understand why they include gzip and lzma compression in a filesystem performance test. BTW, the 8 + head tinderbox runs ZFS on an 64 GB SSD. When I tested ahci last October, I saw a 7% loss of performance with four paralell builds. I haven't tried a newer kernel.
