Potentially interesting for use with ZFS as an LZ4 alternative? I recently did some benchmarking with lz4, gzip-6 and gzip-9 to look at using better compression for archival datasets. However, the overhead of gzip made the system largely unresponsive for days! An algorithm with better compression ratios but less CPU overhead would be a great addition.
