About using multiple liquidsoap instances, we recently implemented an encoding
using an external process, mainly output.{icecast,file}.lame.
The implementation works correctly in 0.9.0 and should be stable in the
current SVN.
I would not really recommend it for production usage yet, but I was interested
to know if this makes a difference when running multiple instance under high
load.
Indeed, this encoding allows a seperate process to perform the encoding
operations, which are clearly a bottleneck for liquidsoap's load. This could
allow a smoothest liquidsoap run while encoding is done in a different process.
However, my tests on running ~10 instances on a dual core did not really show
a difference, so I was interested to know if it makes a difference in your
situations.
