+## Performance
+
+Packing/extracting a 6.1 GB with 2496 directories and 2398 files yields the following results on my Macbook Air
+
+* tar-stream (using [tar-fs](https://github.com/mafintosh/tar-fs)): 34.261 ms
+* [node-tar](https://github.com/isaacs/node-tar): 366.123 ms
+* native tar command: 47.241 ms (this one is a bit unfair as it is piping through processes)
