aRts has a configurable buffer size. If this is small (which it is by default),
it is highly recommended to start arts with realtime rights (run arts wrapper
instead of artsd, or use kcontrol to say so).

It uses the normal aRts/MCOP protocol to stream the data to the soundserver,
which to do so uses a packet oriented protocol over unix domain sockets. There
is some information over various performance/latency aspects in latency.html
in the aRts documentation.
