Difficult to draw conclusions with no code here.

An interesting thing they didn't mention is that Matplotlib's point-in-path code is actually already in C. So this isn't really a case of Rust being X times faster than Python, it's X times faster than some other C algorithm. That's probably why X is only ~4 (they don't actually give a single-thread comparison), instead of ~50.

I expect the Rust code is faster because that code is waaaaay more complicated than what they probably need (https://stackoverflow.com/q/11716268/265521) - e.g. it handles stroke widths.

IMO this result is not very interesting.
