Earlier quoted context omitted.
It’s because modern devs by and large have zero concept of latency differences. I had to explain to people yesterday why an on-disk temporary table in MySQL was slower than an in-memory one. “But the disk is an SSD,” was an actual rebuttal I got. Never mind the fact that this was Aurora, so the “disk” is a slice of (multiple) SSDs exposed over a SAN…
Agree. I've heard people say things like "it is slow because it is not C++". When, in reality, the problem was I/O and N^2 algos.
"It's written in Python and not e.g. in Rust" is simply not relevant in that context.
(For that matter, when uv is asked to pre-compile, while it does some intelligent setup for multiprocessing, it still ultimately invokes the same bytecode compiler - which is part of the Python implementation itself, written in C unless you're using an alternative implementation like PyPy.)
