maybe it will show you other aspects.

OK. 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.
