It has the following characteristics:

  - SOTA decompression throughput in its ratio class\n  - Decent ratios (comparable to LZ4 at high effort levels)\n  - Slow compression\n

\nMost of the gains can be attributed to reducing branches and making decompression very friendly to out-of-order cores, by using a smart format.

Results on the tarred Silesia corpus on Intel x86-64 follow:
