The gain should be 20-25% from what i can estimate. I am just doing some very simple test right now. (default compression preset) core (x86_64) (decompress time) none 552M gzip 186M 12s xz 121M 17s I will add a test for extra later. Even though this might not be a really valid benchmark it show that its defintely worth it. Most people will benefit from a smaller download size which should also comensate the slightly increase decompression time. (I don't think that a lot of people download 65MB within 5s) Note: xz does not seem to use smp; but I have read that this might be possible some day. -- Pierre Schmitz Clemens-August-Straße 76 53115 Bonn Telefon 0228 9716608 Mobil 0160 95269831 Jabber pierre@xxxxxxxxxxxxxxxxxxx WWW http://www.archlinux.de
