[Voyage-linux] Voyage MPD with optimized kernel?

[Gustin Johnson]

A real time kernel is not going to make a noticeable difference on
playback tasks until you start messing with the stream in real time
(like what you would be doing on a DAW).   I would not want to do that
on a Geode :)

What you are really talking about is scheduling.  Scheduling under
Linux (or any OS really) is a complicated beast.  If you are
interested in messing with this, have a look at this site:
http://www.cyberciti.biz/faq/howto-set-real-time-scheduling-priority-process/

You might want to start messing with the nice value of mpd first.

Also as a heads up, the 3.x series of the Linux kernel is taking rt in
a different direction (basically the short short version is that
soft-realtime will be in the generic kernels and should not require
patches).  Interesting times.

Best of luck.
