Do this with uncompress too.
It's not that simple, as you have shown: The difference in the time it took to compress your test data is insignificant and can have been caused by other system activities. Anyway, he's well advised to ask and to seek information since he didn't know what to look for. You can set up your own tests only for things you already know enough about to create such tests, and he is aware of this problem. That's why he's asking. That's what asking is for. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
