Comment(by mrpingouin):
I have reproduced this phenomenon, see attached files. I ran "liquidsoap -
< spikes.liq" script on a small server (low-power CPU) and got
"spikes.log" which logs the time according to gettimeofday and according
to the streaming clock. Then I graphed it using "gnuplot < spikes.plot"
and obtained the attached PNG: it shows that each metadata update causes a
drop of 25 cycles (1 cycle = 0.04s, so that's 1 second). Now, the server
is pretty loaded currently, but this still seems a little high...
