I had a script in another language. It was node, took up >200MB of RAM that I wanted back. "claude, rewrite this in rust". 192MB of memory returned to me.

Solving the big RAM shortage one prompt at a time.

This is sad to see. Node was originally one of the memory efficient options – it’s roots are solving the c10k problem. Mind sharing what libraries/frameworks you were using?

		It was an express server. I don't think c10k is particularly interesting since it mostly just involves having cooperating scheduling. Doesn't really impact flat memory overhead etc. I mean, the binary for node alone, without any libraries etc, is larger than the produced rust binary.

I used to have a bunch of bespoke node express server utilities that I liked to keep running in the background to have access to throughout the day but 40-50mb per process adds up quickly.

I’ve been throwing codex at them and now they’ve all been rewritten in Go - cut down to about 10mb per process.
