Be careful when thinking about performance. It’s true Python isn’t as “fast” in CPU heavy microbenchmarks, but there are lots of real world trade offs to be made here.

If you truly need to handle the kind of CPU bound and high connection count workload today (not some hypothetical future state) where Python struggles, then of course look at alternatives.

Completely agree, often it's better to just spin up an additional server that rewriting in another language.
