Python has nice optimised libs for that, so it's not completely a surprise for that kind of application.

If you're doing generic symbol shuffling with a bit of math, Python is fast-ish to code and horribly slow to run. You can easily waste a lot of performance - and possibly cash - trying to use it for production.

Whether or not you'll save budget by writing your own optimised fast libs in some other lang is a different issue, and very application dependent.
