This plot is also interesting:
- #gzip and #lz4 have fixed (!) and very low RAM usage across levels and compression/decompression
- #xz RAM usage scales with the level from a couple of MBs (0) to nearly a GB (9)
- #zstd RAM usage scales weirdly with level but not as extreme as #xz
#Python #matplotlib
- #gzip has a *really* low memory footprint across all compression levels
- #zstd clearly wins the decompression speed/compression ratio compromise!
- #xz at higher levels is unrivalled in compression ratio
- #lz4 higher levels aren't worth it. #lz4 is also just fast.
This chart includes multithreaded runs for #zstd.
Very interesting! 🧐

- ultra fast compression and decompression, on par with #lz4
- nearly as good a compression ratio as #gzip level 9
- negligible RAM usage
When I need ultra small files though, e.g. for transfer over a slow connection, I'll keep using #xz level 9.
