it's overkill for resolve #6613 :)

[NickM-27]

Maybe, but I agree that many users (like myself) won't have use for these and there's no sense taking up extra time for stats which aren't needed, especially as more and more types of stats are added.

Perhaps we should expand this scope to allow disabling all stats that require spawning external processes. The system page used to be very fast. For example, gpu usage never really changes once things are up and running.

[skrashevich]

Absolutely agree. I was precisely endeavoring to minimize the invocation of external processes during the statistics calculations (#6298, #6344, #6359).
