Subject: [linux-audio-dev] user lowlatency kernel experience

hello,
would just like to tell you of my experience with a low-latency kernel.
i tried kernel 245 with the low-latency patch. to test the system i
tried using timidity and csound at the same time, driven by jazz.
both csound and timidity run as root with the high priority scheduling
activated.
my experience was that it became very easy to hang the system.if csound
got to many notes, it would render forever end never return, thus
effectively hanging my machine.
since the increase in performance wasnt really all that great in my
case, i have now disabled the low-latency flag, fortunately this can be
done without recompiling the kernel.
so, since people here seem to think that the low-latency kernel is
really great, i suspect i have missed something. is there a way to get
processes to get sceduled promptly, but at the same time not hog the cpu
if they try?
