The numbers I know about are wrong: zstd always beats gzip for compression ratio.
I will need to do my own testing.
It compresses about as well as lz4, but more slowly. It also decompresses more slowly.
It is faster than zstd -1, but compresses less well.
It is possible that it does better with certain kinds of data, but 12x remains implausible.
Apparently the current file format has suffix ".sz".
