Icecast uses trivial amounts of CPU. Don't worry about that.
The only thing that will require any substantial amount of cpu here is
ices2, for encoding things. How much cpu that will require depends on:
number of separate streams, number of channels, and sampling rate.
You can get a rough estimate of what this will require by using a
vorbis encoder such as oggenc to encode a file with the same
parameters (sample rate, channel count) as you intend your stream to
For a single stream, you won't find the amount of cpu used too bad.
