If we judge only performance, we will select lz4. However, we should think another important factor which is software
robustness,achievement, bug
 
fix history, and etc... If we see unknown bugs, can we fix it or improve
algorithm? It seems very difficult, because we only use it and don't
understand algorihtms. Therefore, I think that we had better to select
robust and having more user software.
