The bigger server I have has 150 max channels during peak hours and has a
max load of 0.5 with 24 cores. When I was using a 4 cores server with the
same number of channels, I get a load of 3 ... so the load x core relation
is valid. I think it will be good to have a load not over 4 for a 4 core
server, so you can have at least 200 active channels on the server. If you
accept more load, then you can get more channels.
