I think this may not be a very high bar. zippy in Nim claims to be about 1.5x to 2.0x faster than zlib: https://github.com/guzba/zippy I think there are also faster zlib's around in C than the standard install one, such as https://github.com/ebiggers/libdeflate (EDIT: also mentioned elsethread https://news.ycombinator.com/item?id=43381768 by mananaysiempre) zlib itself seems pretty antiquated/outdated these days, but it does remain popular, even as a basis for newer parallel-friendly formats such as https://www.htslib.org/doc/bgzip.html
In Zlib-rs is faster than C

Nothing is without the cons. I would say: * Libraries: there is no NPM ecosystem to get anything you need. * Stack-overflow: If you looking for a aswers there might not be anyone who encounters it before. You might have to dig really deep to find some thing. * Some times you might run into a compiler bug usually related with performance of the generated code. Like it generates correct code bug it's slow for no reason and minor changes to the code make it fast again. * Relying on OpenSSL especially v3 especially on windows is a big problem, but thats more on openSSL i think. I actually wrote a library around this that uses platforms HTTP/SSL instead: https://github.com/treeform/puppy * Not having HTTP gzip support in standard library. You can always work around with zippy though: https://github.com/guzba/zippy * async stack traces are real

ly hard to read. * not enough docs around the different ways to do threading. There is no one solution some times you want a quick thing, some times you are doing CPU tasks other times you are doing network tasks (where async is better). But many big languages struggle here, there is no one fits all threading solution. It's definitely not style case insensitivity which everyone loves to bike-shed about.
In I enjoy using the Nim programming language at Reddit
