a simple explanation but not 100% correct is that even if your code is made to run in parallel using threads, it will never use more than 1 core in your computer.

getting rid of the GIL will let it use all the cores in the processor.

the multiprocessing module "solved" this problem by forking processes instead of threads, but it's not ideal for a lot of workloads.
