New codec misa77 decodes 2x faster than LZ4 with better ratios
misa77 is a new codec that achieves decompression speeds over 5 GB/s, doubling LZ4's throughput while maintaining comparable or better compression ratios. It uses a branch-reducing format optimized for modern out-of-order CPUs. Compression is slower, but the focus is on decompression performance for read-heavy workloads.
Meridian48 take
This is a genuine performance leap for decompression, but the slow compression limits its use to write-once, read-often scenarios.
