compress: Optimized Go Compression Packages (5.7k stars) What it does All text below is quoted directly from the project README. >Optimized Go Compression Packages This package provides various compression algorithms: - zstandard compression and decompression in pure Go. - S2 is a high performance replacement for Snappy. - Optimized deflate packages which can be used as a dropin replacement for gzip, zip and zlib. - snappy is a drop-in replacement for github.com/golang/snappy offering better compression and concurrent streams. - lzw is a drop-in replacement for compress/lzw with 1.4-4x faster decompression and 1.1-2.7x faster compression, depending on the data. - huff0 and FSE implementations for raw entropy encoding. - gzhttp Provides client and server wrappers for handling gzipped/zstd HTTP requests efficiently. - pgzip is a separate package that provides a very fast parallel gzip implementation. >Use go get github.com/klauspost/compress@latest to add it to your project.

so you joke about this, but actually Opus and Fable have rewritten substantial chunks of github.com/klauspost/compress/blob/master/zstd/_g… in the past few months, for better performance (and it actually worked!).
