How to write slow Rust code – Part 2
renato.athaydes.comIt's always sad to see someone get burnt by the internet, I wish him, and also those who criticised him, well.
On a brighter note, I appreciate the noob-friendly explanations. It made it really easy to follow along.
I'm also really curious about how Java achieves better stdout performance. I hope we get to apply the lessons to other environments too! I didn't read all of it, so perhaps there's a clue in @bugaevc's PR[1] mentioned in the article.

[1] did in fact talk about and link to a Rust discussion PR[2] about the stdout perf issue. Essentially Rust always flushes stdout for every line of output, whereas other languages like Python tend to buffer larger blocks before flushing.
