Sometimes, some functions of your script are taking up time and you would like to optimize those. We are not speaking here about the encoding of streams, which usually takes the vast majority of the spent computing power, but of functions written directly in Liquidsoap. In order to understand those better, Liquidsoap has a profiler which records all the function calls. It can be enabled with
(or by passing the
--profile commandline flag of
Liquidsoap) and the statistics can be obtained with
It will output something like
function self total calls + 0.359139919281 0.359139919281 302000 list.add 0.324638843536 442.74707818 202000 if 0.242718935013 442.951756954 102002 list.cons 0.230906486511 442.277146816 101000
where each lines consists of a function, the time spent in the functions, the time spent in the function and the functions it has called and the number of calls to the function.
