[proaudio] Has anyone experimented with different rlimits values in /etc/security/limits.conf?

["Colin Shapiro" <cmshapiro@xxxxxxxxx>]

Greetings,

I was just wondering if anyone has played around with different values
for the rlimits-aware PAM.  I'm asking, because I'm wondering if
they can be altered for better Jack performance.

I have an AMD64 X2 with 2GB of RAM, and although Jack performs much
better now after I've rebuilt and optimized my system, I still
consistently get an xrun after ~30 minutes of using LinuxSampler with
the PMI Bösendorfer 290 Gig-v3 sample library.

I've changed the defaults:


@audio             -    rtprio 100

@audio    -          nice           -10

@audio             -          memlock         250000

...to this:


@audio             -          rtprio 100

@audio    -          nice           -20

@audio             -          memlock 1024000

...and I *think* (although I could be imagining things) that it's
working a little better.  But I'm wondering if anyone else has any
insight to offer on this.

Thanks,

Colin
