Icecast2 doesn't (like some servers) send an initial fast burst. It sends in
real time. This drastically reduces latency, at the cost of slow starts if
the client does too much pre-buffering (most clients do on low-bitrate
Fast-start will probably be added eventually, for those that really want it,
but it'll be off by default. The right way to fix this 'problem' is to
convince client authors that pre-buffering a fixed number of bytes (rather
than a length of time) is the wrong thing to do, since it typically means
you're buffering too little on high-bitrate streams, and too much on

Yes, this will reduce the peak latency, but not the typical case.
