[Skimmertalk] CPU needs for skimmer server

It also depends a little on the rf environment, if you have a lot of 
squirgles and birdies and you use a wide rx bandwidth that all adds to 
processor load. By experimentation here I also believe high processor load 
impacts decoder accuracy to some extent.

If you want multi band high bandwidth decoding +and+ use the pc for other 
tasks at the same time you do need a fair bit of cpu horsepower.

IMHO Skimmer should be on its own dedicated pc as that relaxes the 
requirement a little.
