Hammer 2 now uses LZ4 compression by default. It also uses a new CRC algorithm that performs much better, and there’s numbers to prove it. It helps iSCSI too. When I say new, it appears to be from the 1980s? I may be looking at the wrong place.

This looks really exciting guys! I wonder if the hammer2 will use the same method for deduplication found in hammer1?
