Simple Compression Benchmarks

This Gist looks at the following lossless compression utilities, all available as Debian packages:

brotli, bzip2, gzip, lbzip2, lz4, lzip, lzma, lzop, pbzip2, pigz, plzip, pxz, pzstd, xz, zstd

Benchmark

A simple Bash script compresses the Canterbury Corpus (provided) with every compression level for each of the algorithms, with the default level for each printed. It produces a Github-flavored Markdown table, such as results.md as shipped here from my workstation.

Even though it's a Markdown table, you can still process it with standard Unix utilities, as it's pipe-delimited. Something like printing the top-10 fastest compressors:

$ sort -t '|' -k 2 -nr results.md | head
pigz -0 | 258525433.154 | 2821476 | 85109679.301 |
lz4 -1 | 75650475.579 | 1229064 | 55192298.771 | default
lzop -3 | 71676886.832 | 1199867 | 16830860.795 | default
lzop -2 | 71558916.811 | 1199867 | 38213867.999 |
lzop -4 | 68617624.789 | 1199867 | 29681383.024 |
lzop -1 | 68561204.698 | 1210489 | 35648694.633 |
lzop -5 | 67990840.618 | 1199867 | 41306498.621 |
lzop -6 | 67616475.385 | 1199867 | 44747936.210 |
lz4 -2 | 61547959.238 | 1229064 | 77693145.754 |
pigz -1 | 42988502.188 | 866357 | 29336060.575 |

Printing the tightest compression results between brotli(1) and zstd(1):

$ grep -E '^(brotli|zstd)' results.md | sort -t '|' -k 3 -n | head  
brotli -11 | 53483.277 | 495859 | 9783745.946 | default
zstd --ultra -21 | 413327.544 | 516708 | 14872758.711 |
zstd --ultra -22 | 262693.526 | 516719 | 25229871.714 |
zstd -19 | 427172.435 | 516752 | 14235727.584 |
zstd --ultra -20 | 460621.272 | 516752 | 24879831.001 |
brotli -10 | 120502.209 | 518406 | 26550577.522 |
zstd -18 | 628484.580 | 518962 | 13812735.470 |
zstd -17 | 977636.888 | 525979 | 16590003.177 |
zstd -16 | 1083873.266 | 535615 | 26475770.306 |
brotli -9 | 1811053.437 | 587153 | 19998655.296 |

Et cetera. I'm sure you can figure out how to handle the headers separately, or format to your liking.
