I just tried a tar file of a git clone of the linux kernel sources where the most recent commit is 72c395024dac5e215136cbff793455f065603b06 (early Feb of this year). zstd -19 got a slightly smaller size (3582930348 bytes vs bz3 -b 511's 3597411687 bytes or 0.4% advantage to zstd). More significantly 4-core zstd decompression was 2.05 seconds vs a whopping 297 seconds for bzip3 -dj4 - 145x or over 2 orders of magnitude slower (about as much time to decode as to encode in the first place). bzip3 1.5.3 compiled with gcc-16.1.0. Granted, the .git objects are all compressed already and uncompressed tar-ball was only 5426667520 bytes, but even so...A lot of people care about fast(-ish) decompression. Maybe I did something wrong? Maybe `rm -rf .git` first would be a better benchmark?
