Excerpts from Rui Nuno Capela's message of 2010-06-06 13:37:33 +0200:

At least the default depends, it's 300 here, but I guess that doesn't
make a hell of a difference :)

> however, i remember some mixed reports that the hrtimer is a scarce

Now that I have a hrtimer capable machine I gave it a shot with jack,
the results were weird to say the least.

I got jackd -c h to work without complains, but then nothing else could
access the hrtimer, neither a2jmidid nor synths that try to do the same.
The really weird part however started when I connected a jack midi
sequencer to my hardware piano. Once the piano was connected to the
sequencers in and the sequencers out back to the piano I suddenly got
tons of xruns. I didn't experiment further to narrow down in which cases
it happens and in which it doesn't, but I'm sure it's in some way
related to jack running with jackd -c h.
I should probably mention that I did this test with tschack-git.
Just thought I drop this little piece of experience here.
