This was using an Adaptec 1502 card (I tried to find one of the _least_
intelligent SCSI cards for this to test interrupt latency, etc), stock
2.1.105 and 2.0.34 was one of the late pre's (15, I think).
2.0.34 used rev 1.18 of the aha152x driver, and 2.1.105 uses 1.7. I'm not
sure how much of the speedup can be attributed to overall SCSI improvements
vs. driver improvements, but the numbers are impressive, none the less.
Good work, everyone!
