There’s numpy in the middle, so bits are outside python. The vast majority of the code is Python though and the performance gains come from being strategic about the architecture.

My point is that for most usecases you can go a lot further by looking at the code that’s running rather than the language that’s running it.

I think python have the best libraries you can buy, and that makes python a very strong choice if you do not suffer the NIH syndrom or do not need extremely fast code (python is fast enough now).

One big issue i have though: the lack of easy multithreading reduce your possibilities, or at least limit your creativity: you will often choose to use async/await (and sometimes use signals) rather than use producer-consumer designs, which are often the optimal solutions.
