I use it at work for a script that parses and analyzes some log files in an unusual format. Wrote a naive parser with a parsing combinator library. It was too slow to be usable with CPython. Tried PyPy and got a 50x speed increase (yes, 50 times faster). Very happy with the results, actually =)

Thanks for the feedback. It does seem like parsing logs and simulations is a sweet spot for PyPy

Simulations are, at least in my experience, numba’s [0] wheelhouse.

what cpython version and OS was that? I'd be very surprised if modern Python 3.11 has anything an order of magnitude slower like that. things have gotten much faster over the years in cpython
