In fact, it's slightly slower on my system: % time gzip -9 < /tmp/files.tar > /tmp/files.tar.gz real 0m0.010s user 0m0.000s sys 0m0.000s % time pigz -9 < /tmp/files.tar > /tmp/files.tar.gz real 0m0.012s user 0m0.010s sys 0m0.010s For the xfstests.tar.gz file, it does make sense; it cuts down the compression time form 3 seconds to half a second. That's fair, although at least in my workflow I'm not recreating the xfstests.tar.gz file all that often.
