Hello
I upgraded to liquidsoap 1.0.0 and the performance is better. The cpu is on the same levels but
i take far fewer  "we must catch time..." messages.

After i moved to 1.0.0 i don't have the problem with the high cpu at the first track.
With 0.9.2 to add a  5 seconds track of sine wave at the beginning "solve" the problem with the high cpu at the first track.
I will try the hardor output or to run a script from icecast's on connect to "pause" the liquidsoap.

Thanks for your tips.
