It doesn't compare itself against bsc, which feels a bit poor IMO given it's using Grebnov's libsais and LZP algorithm (he's the author of libbsc).

On my own benchmarks, it's basically comparable size (about 0.1% smaller than bsc), comparable encode speeds, and about half the decode speed. Plus bsc has better multi-threading capability when dealing with large blocks.

Also see https://quixdb.github.io/squash-benchmark/unstable/ (and without /unstable for more system types) for various charts. No bzip3 there yet though.
