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zlib itself seems pretty antiquated/outdated these days, but it does remain popular, even as a basis for newer parallel-friendly formats such as https://www.htslib.org/doc/bgzip.html

The bar here is not zlib, it's zlib-ng, which aims primarily for performance.

libdeflate is an impressive library, but it doesn't help if you need to stream data rather than having it all in memory at once.
