Show HN: misa77 - a codec that decodes 2x faster than LZ4 (at better ratios)
1 min read
I've spent the last few months working on this codec.
It has the following characteristics:
- SOTA decompression throughput in its ratio class
- Decent ratios (comparable to LZ4 at high effort levels)
- Slow compression
Most 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:
