program comp-ratio comp-time decomp-time pigz -1 40.3% 26.92s 20.31s lz4 -c2t4 43.9% 52.72s 5.84s info-zip -1 41.3% 122.31s 119.81s More relevant would be a comparison with gzip -1, lzop, snappy and rolz. Also the test data is mixed. It is not very helpful to see where this algorithm shines. Also note the memory usage shots up from 5m/2m for info-zip -1 to 46m/42m for the specific case of lz4 you picked. EDIT: also bzip2 seems to be paticularly bad for this specific dataset, other algorithms in that category get better compression ratios. Added pigz to the comparison (info-zip with pthreads).
