Bzip is slower than zstd and doesn’t compress as well as xz. There’s no place for it.
10 years ago we look at replacing gzip archives with bzip. It was just too slow for the incremental space saving gains offered. Creating bzip archives took forever. I know xz is "better", but we still just gzip everywhere.
Article has the numbers for their input:
uncompressed: 327005
(gzip) zopfli --i100: 75882
zstd -22 --long --ultra: 69018
xz -9: 67940
brotli -Z: 67859
lzip -9: 67651
bzip2 -9: 63727
bzip3: 61067
You can pry bzip from my dead cold hands.
