[Skimmertalk] Trying to optimize CPU while skimming - More FT8 questions

My computer is running pretty heavy and I was taking a closer look in order to optimize the resources needed by skimming on 8 bands for FT8 and 16 on CW. A couple of things that I do not understand:

Why are there 1 GB of data collected in WAV files by the WSJT-X instances (see screen shot at https://photos.app.goo.gl/8tvXLn5JSWEoizWm8)?

And each FT8 band causes 3 processes to run:
Wsjt-X.exe                     1 - 2 % CPU
jt9.exe                            1 % with spike at 20%, presumably when decoding happens?
cwsl_ssbwave.exe       1 - 3 % CPU

Is that adequate? Seems pretty power hungry. Is there anything that can be optimized?  Remember, I am running CW Skimmer as well, which also need 10 - 20 % of CPU.

I am running the computer with the Performance power profile.
Would it help to optimize for background services or foreground apps?

Thanks
