Feature or enhancement

Proposal:

randint is a commonly needed function, but it is fairly slow (compared to random.random).
Maybe it would be good to port couple of lower level functions to C.
But for the time being, this small edit results in 20% better performance by avoiding unnecessary abstractions.

Has this already been discussed elsewhere?

    Adding C implementations for random has been rejected before. See #126149 for previous discussion
