Advanced stuff

How to deal with more cores

Parallelism: CPU Bound => Multi Processing

  • you're running stuff in parallel and taking advance of multiple CPUs

Concurrency: I/O Bound, Fast I/O, Limited Number of Connections => Multi Threading

  • concurrently running more tasks on one thread, context switching

Ansynchro: I/O Bound, Slow I/O, Many connections => Asyncio

  • using async/awaits, waiting thread can let further code continue executing and the results from awaiting one are either received or needed

NOTE: low level languages such as C/C++, C#, Java achieve native parallelism computing by using threads, higher ones such as SnekTM🐍 and Google's abomination of Go locks down interpreters (GIL) and forces you to use further libraries (Multiprocessing) or tedious workarounds ((G|c)routines)
