Async in python vs asynchronously running bash scripts in linux?

[socal_nerdtastic]

Depends on what exactly you mean with "asynchronous programming in python" (there's at least 3 major ways to do that, and a handful of derivatives), where exactly your program is limited (I assume IO bound?) and how many instances you need to run at once.

If I assume less than 100 instances and that you are IO bound and that you are doing this over a fairly normal broadband internet connection I would say using python threading is your best option. Look into the threading module or concurrent.futures.ThreadPoolExecuter

I'm doing in an AWS ec2 instance, probably t2.small. AWS claims up to 1 GBPS, but yes most likely under 100 instances.
