The RT patch is way to improve scheduling latencies.

The cgroup mechanism is a way to control access to realtime scheduling.

Hi all!

In the past few months I've been fiddling with the kernel config to
get the best latency out of my laptop (core2 t6400, 2GHz 1MB L2, 4GB
of RAM).
The best settings I've got so far are 128*3 with a sample rate of
48000Hz. All of this with the rt-patch and following the guide in the
linux audio wiki.

My question is regarding the method described here
http://p=
roaudio.tuxfamily.org/wiki/index.php?title=3DDAW_Digital_Audio_Workstation#=
Instructions_for_3.x_Kernels

I've seen this described in many a forum, and people say they got
better results with it than with the rt-patch.

Do you have any experiences with the cgroups solution? Is it stable
enough for live performance?

I will be testing it some time in the future, but I thought it would
be a good idea to fire up the discussion here and make it for a common
profit.

Thanks a lot to all of you. It's great to know there's a place for =
