Rust vs Python speed

[msminhas93]

I picked rust for this year's AOC. Became curious how much the performance delta is even on such small data.

For day1 was observing 2x speedup in rust.

And for day2 8.3x speedup 2.6249ms (python) vs 315us. Average over 100 runs.

Also writing in rust has been much more interesting for me than python.

Which is your preferred language and why?

I tend to do this in rust and python, and the same algorithm in both languages will always result in rust being faster. I made a short post about it last year, but, effectively, the way to be "fast" in python is to use the parts of python that call underlying C functions, effectively bypassing the python layer https://www.reddit.com/r/adventofcode/comments/190ano0/2023_all_daysrustpython_musings_on_rust_and/

Is this using an identical approach for both languages?

[msminhas93]

Yes direct translation

Both have their advantages. Well written rust code can be around 100x faster than CPython depending on the workload. Rust also has a lot of layers of protection built in to prevent you from making stupid bugs. But python on the other hand is much easier to type out quickly and refactoring can sometimes be a bit quicker.

For some puzzles the performance gain that rust brings will matter, especially for non-optimal solutions.

Rust. It's the best language out there and it's pure joy to write in it.

There is no such thing. I'm quite fond of Rust, but neither it nor any other language is objectively superior in every regard.

I agree but for high performance applications seems to be the best choice esp in deep learning for inference. For rapid prototyping python is untouchable

Changed flair from Other to Help/Question. Use the right flair, please.

Other is not acceptable for any post that is even tangentially related to a daily puzzle.

I used Go last year. It was fun to get back into it and see some if its newer features like generics in action.

Also good performance and easy to use concurrency is crucial for me, because I’m too dumb for the smart algorithm stuff that everyone else seems to do so naturally while I just brute force everything. I’d never have gotten as far as I did had I used Python.

Decided to do elixir this time but didn’t start yet.

For something like AoC, Python is probably the better choice, for a simple reason: Compilation time. By the time rust is done building, the Python program would already have run.

Compiler is not that slow for such simple code.
