Is R using 0% or 25%?
Again, if R was using 25% while showing the prompt and waiting for
user input, that would be a bug in R.
Or do you mean R is using 0% and total CPU usage *temporarily*
increases 25% *while* R is running?
If so, this could be the result of some security feature...? not sure
because this is outside my area...
I just found the following feature.
If you open powershell, one can run: ps | sort -desc cpu
This could be used if you want to show people what's happening.
PS C:\Users\spurdle> ps | sort -desc cpu
Handles NPM(K) PM(K) WS(K) CPU(s) Id SI ProcessName

Diverging, I can't figure out how to permanently stop Lenovo and Skype
processes, or why chrome (and edge) need so many copies of
themselves...
Anyway, the plan is to shift to Debian or OpenIndianna, and run
ReactOS via virtualization...
