DNA researchers developed a parallel format for gzip they call "bgzip" ( https://learngenomics.dev/docs/genomic-file-formats/compress... ) that makes data seem less trapped behind a decompression perf wall. Zstd is still a bit faster (but < ~2X) and also gets better compression ratios (https://forum.nim-lang.org/t/5103#32269)
