Thanks for all the info Midnight!! I guess I wont jack with jack
As for the CPU, I see its also dependent on what the source is. From USB I stay mostly below 20%, from radio if the stream is higher then CPU also goes up in relation. So far I have kept the performance setting, but cant really tell if its "better".
I set it in rc.local as well as doing a bunch of other things to try and make for better performance....as best I can.
