Does it make sense to use Pool on a single core processor?

Question

Python

Tell me, does it make sense to use multiprocessing.pool on a virtual machine with 1 CPU core? On my 4th core process, I exposed map(4) and map(40) there is a difference. Although they write that it is more optimal to use the number of "processes" = the number of cores.

Answer 1

It only makes sense if each thread consumes almost no resources and you want to utilize the entire CPU

Answer 2

Does it make sense to use Pool on a single core processor?

Yes, processes can be added until the CPU consumes less than 100% (or until it hits io / network / disk)

Answer 3

You never know what they write about the spherical in a vacuum.
Take your specific software.
You freeze on it.
Believe your eyes.
