I just released about 2 years of work on improving compression with a fixed encoding LZ77 style compressor.<p>Our goal was to improve compression by combining and tweaking the best aspects of LZ4 and Snappy.<p>The package provides Block (up to 8MB) and Stream Compression. Both compression and decompression have amd64 assembly that provides speeds of multiple GB - typical at memory throughput limits. But even the pure Go versions outperform the alternatives.<p>Full specification available.
