Hi,
I am in the process of setting up an airtime server for a small radio station which will running for a week from the middle of a Scout Jamboree.
For this reason we have managed to acquire a small server which we were hoping would do the job. I have got airtime installed and running but I am having a bit of trouble with performance.
The machine has a 1.3Ghz processor with 1GB of RAM.
When running airtime with 1 x Alsa output and 1 x 64kbps OGG stream. When running both of these I sometimes hear 'skipping' on the soundcard output and the odd gap in the stream. When I open the airtime webpage the soundcard output skips consistently and the stream drops out more frequently.
Looking at the processes on the system it appears that airtime-liquidsoap is using 50% CPU on average, peaking at about 65% CPU. apache2 is also utilising quite a high percentage, peaking at about 25% CPU.
Does anyone have any suggestions as to why the CPU usage could be so high, and if there is anything we can do to reduce it? Ideally I don't want to have to reduce stream quality or anything.
(Also - the UI seems to be quite unresponsive which I am guessing is a related issue).
Thanks in advance.
