misa77 - a codec that decodes 2x faster than LZ4

A developer has created a new codec called misa77 that decodes 2x faster than LZ4. The codec has been designed to reduce branches and make decompression friendly to out-of-order cores. The developer has shared the results of testing the codec on the tarred Silesia corpus.

Why it matters

This codec has the potential to improve the performance of applications that rely on compression and decompression. The fact that it is open-source and available on GitHub makes it accessible to other developers who can build upon and improve it.

Try thisTry using the misa77 codec in your own projects to see if it can improve performance. You can find the codec on GitHub and test it with your own data.
