How is the suse 2.4 kernel patched in these tests? A form of the low-latency patch? I made some latency improvements to 2.6's ext3 recently, so it should be performing significantly better than it was in 2.6.0-test9. I'll do some more checks on 2.6 but as far as I know, it's performing OK. If Jack is indeed running with realtime policy I'd be suspecting that something other than the normal spends-too-long-in-the-kernel problem is occurring. Could someone give me a really simple description of how to obtain Jack, and how to get it going sufficiently to demonstrate these problems? Thanks.
