Martin is right, there is no difference in CPU utilization (on the Red
Pitaya itself) when RTTY Skimming is enabled.

You can display the amount of CPU usage via the *top* command after logging
in to the Red Pitaya with PuTTY.  Skimming 6 bands x 192 kHz, it averages
around 41% CPU Utilization.  The *uptime* command will also display the
load averages for the past 1, 5, and 15m minute intervals:

00:44:36 up 15 days,  1:08,  2 users,  load average: 0.43, 0.43, 0.41

(43%, 43%, and 41%).

The Red Pitaya has plenty of horsepower for 6 band Skimming.  Cooling is
always a good idea.

If you switch to 96 KHz skimming, the CPU utilization does go down somewhat.
