what is the benefit of threadpool though? am I understanding it correctly that due to GIL, python will just keep switching the threads, so instead of running A then B both at 100% speed, both will run concurrently at 50% speed (+/- overhead)?

Only if you're CPU bound, but usually your webserver is blocking on disk IO or database calls or whatever, not calculating stuff, in which case the GIL doesn't matter.

You can get benefits with IO bound work.
