Below are some standard C libraries shipped as part of Debian 11 Bullseye as of January 2023. The numbers aren't directly comparable, as these libraries have a richer API, especially in providing an encoder and not just a decoder. Still, it is a reference point for e.g. Wuffs (adler32 + crc32 + deflate + gzip + zlib) vs libz and Wuffs (gif + lzw) vs libgif.
