The best way to figure out what is causing all those decoders is to use CW
Skimmer, rather than Skimmer Server, so you can view and listen to every
signal the Skimmer is "seeing" and marking with a "decoder dot".  You can
view them on a waterfall display and listen to them on the PC speaker
output or headphones.

Chances are it's a just local noise source such as unshielded Ethernet
cables, a switching power supply, or broadcast harmonics generating many
carriers on the band.

As for RTTY Skimmer, you can run it on slower machines, and it should
gracefully scale back or "throttle" it's usage if there isn't enough
horsepower for it to create all of the required RTTY decoders.
