I love playing around with #compression

In this case, it's all text-based data in csv and xml formats.

Size:

32,696,320 202411.tar
 4,384,020 202411.tar.bz2
 4,015,912 202411.tar.zst
 3,878,583 202411.tar.bz3
 3,730,416 202411.tar.xz

zstd was invoked using zstd --ultra -22
xz was invoked using xz -9e
bzip2 was invoked using bzip2 -9
bzip3 has no compression level options

Speed:

zstd    54.31user 0.25system 0:54.60elapsed 99%CPU

Maximum memory usage (RSS):

zstd    706,312
xz      300,480
bzip3    75,996
bzip2     7,680

*RSS sampled up to ten times per second during execution of the commands in question

#bzip3 is freaking amazing, yo.
