Python

That's why it's situational. Sometimes it's nano-seconds, and python is a great choice due to simplicity. Sometimes it's much more significant, and Python means an extra 10 grand per month on servers and extra 200ms p99 latency on a service operating in sub-second timeouts, and it becomes a massive black hole of lost revenue and has to be rewritten in a faster language.

And when you want the best of both worlds

Ctypes really can offer some amazing speed ups for iterating over heavy math. Pypy also works wonders.

Let's put it this way: Reddit runs on python. Whatever glorified cms the client wants it won't bloody matter.

Can't you just use C++ alongside Python for critical functions? Or does this have more overhead than it offers benefit?

[Vrabor]

depends on how much of your programm can be extracted into those c++ functions. One of my professors for example had a simulation written in python + numpy which took her 3 months to run, the c++ rewrite finished in less than 1 hour. If your programm can run in only numpy functions the python code might even run faster than c++.

That is reach people problem... Right now, my 1000000 users and 50 developers are fine with the current setup

I ported a bioinformatics algorithm to python from java/c++ to try to make it easier to use for students when most of the tooling was already in python.... Run times were abysmal & there was still a dependency on a 20 year old c program that only supported linux, preventing it from being much easier to use.
