improved with a higher kern.hz rating. Unless the future holds an emu20k2,
there will be RAM used from the motherboard.
1. I will need a real-time or a faster kernel- hence the high rate wanted-
because the devices to be built will be used in an active environment: art,
music, audio control.
2. Any system with limited memory and a low CPU hertz rate benefits from
the higher kern.hz setting.
rather opposite. more kern.hz=more interrupts.
3. Why not? If it works for PowerPC, SPARC64, AMD64, and i386 then it may
work for other architectures.
4. Some applications may be ran from within a jail.

Well, why is it reducing latency? That's the thing you should investigate.
Is it because processes aren't getting enough time? or too much time?
Or the audio device isn't getting enough time to run? etc.

This is the thread that I was referring to earlier. Since the patch is
for
2009, what are the chances it would work with 10.x or 9.x?
On PowerPC machines with a low MHz rate- or any machine with a CPU rate
of
800 MHz or less- increasing the kern.hz improves performance and cuts
down
on latency. I am building audio applications and suites that are used in
different projects. A G3 based machine should be able to run a kernel
with
kern.hz=5000 with no problem. Unfortunately, this cannot be done.
@PowerPC: some of you may find that performance does increase at a higher
kern.hz rate.
@Hackers & Current: What's the chance that the default rate limit can be
raised to 5k?
