 ### Performance
 
-Benchmarks can be run comparing different Zip implementations. My benchmarking shows this library performs well but it is not as fast as zlib itself (not a surprise). Check the performance yourself by running [tests/benchmark.nim](https://github.com/guzba/zippy/blob/master/tests/benchmark.nim).
