I'll try and see if i can get that test of his to run.. That would be very interesting. Mark did a fine piece of work making these comparisons. His tests were run on 2.4 at -p256 -n3. Since we can do much lower latencies now, -p64 -n2 would be interesting. As a baseline, the vanilla 2.6.10 kernel runs pretty well. Several kernel developers tell me that recent versions of ext3 are much better in both disk performance and latency. I'd love to see XFS and JFS numbers, too. IIRC, Mark was running Benno Senoner's latency test... http://www.gardena.net/benno/linux/audio/ -- joq
