From the pigz documentation: "Decompression can't be parallelized, at least not without specially prepared deflate streams for that purpose. As a result, pigz uses a single thread (the main thread) for decompression, but will create three other threads for reading, writing, and check calculation, which can speed up decompression under some circumstances." | |

Try comparing the output of time tar xf dir.tar.gz and of time pigz -cd dir.tar.gz | tar xf - (on my 4-core CPU it takes a bit less than half the time). | |
