First results of my #compression algorithm benchmark run on a 72MB CSV file. It seems #zstd really has something for everybody, though it can't reach #xz's insane (but slow) compression ratios at maximum settings.

This chart includes multithreaded runs for #zstd.

Very interesting! 🧐

Input file used for the benchmark. A CSV file with a very long header, then columns with a unix timestamp in the first column, then only one column is filled in every row, giving a cascading look to the file. It's atmospheric temperature, humidity and pressure data from several Sensirion SCD30 sensors.
