Decoding the mp3 with the mad mp3 library takes around 4% (try madplay),
which is exactly the load I get with gst-launch and osssink, too.
Perhaps it is a problem with arts?
I don't know of anyone having done performance analysis of our code.

There is currently no roadmap when 0.7 will become the next stable version
or when we are going to do pre-releases. So you're developing against a
CVS version for now. Marlin is such an application.
The CVS version has a lot of neat additions and I would consider it more
stable and less buggy. So apart from that problem with releases and the
fact that CVS might have some incompatible changes now and then, I'd
deffinitely use it.
