Around 4% on a 450MHz Celeron. Sound played by xmms through xmmsarts and
ALSA below it all was flawless even during compiles. Opening links in
new windows in Konqueror made it stutter slightly. There was a simple
remedy, if you're not morally or otherwise opposed to it: make
/usr/bin/artswrapper suid. Additionally, I made it executable only by
group audio and added myself to that group. In order not to lose these
changes after an upgrade I made them permantent with
$ dpkg-statoverride --add root audio 4710 /usr/bin/artswrapper
artswrapper is a very small program that tries to switch to realtime
scheduling (what it needs root privs for) and then starts artsd with
the id of the user who started artswrapper. Therefore, artsd itself
does not run with root privileges.
Don't forget to enable "Run soundserver with realtime priority" in the
Sound Server Preferences. Otherwise you won't get the intended effect.
