Hi folks,
I've just benchmarked low-latency behaviour of kernel 2.4.0-test2
what should I say: although a bit better than standard 2.2.x kernels
not much has changed (still worst case latencies around 100msec).
(judging from the graphs, disk I/O throughput compared to 2.2.x ,
is lower too, but that is another issue)
see the graphs here:

for comparison same box on 2.2.10 + Ingo's low latency patches:
http://www.gardena.net/benno/linux/audio/audio3x128-cpu80/3x128.html
this kernel delivers up to 60times lower latencies than 2-4.0-test2 (100msec vs
1.5ms ) :-)
Benno.
