Yes, of course. I think we can take some time to let it bake, as there is not an immediate need, and when 5.0 comes out we can move it to core and then rebuild libarchive with support for both.
Sure, no need to hurry. Slackware has achieved a decrease of size from 1,9GB to 1,4GB of their main repo. Our ratio should be lower as we don't have source packages in our repos. But it should be easy to test once the tools are ready. (du -h;gunzip *.gz;xz *.tar;du -h)
Just for the record, Slackware didnt move the sources to xz. Just the compiled packages. The descrease in size you are reffering to is more or less correct. My local rsynced tree is 1.6Gb with .xz while it was around 2.0Gb with .tgz. 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@jabber.archlinux.de WWW http://www.archlinux.de
