I am not absolutely sure which metadata the discussion is about, but I assume something like this: http://download.opensuse.org/update/12.1/repodata/b55a3d182b709c77784693f284...
I just tested, the original gzip compressed version is 7.7MB. Using xz for compression instead reduces the file size to 2.2MB.
Wow, that's a huge difference.
My connection isn't as slow as the GFW, but I still have to wait a significant while if I have to download those metadata files again (quite unusual for big repos, but happens from time to time). Shrinking the download 3.5 times is quite significant.
The funny thing is I haven't seen that huge compression ratio improvement in source tarballs. Must be something specific to xml.
The LZMA algorythm kicks a$$. In UH it readuces the sources from 170Mbs to 120Mb ;) GNOME is using now xz, and rpm 4.10.0 supports it natively. It's coming dude :)
rpm already knows xzdio since 4.8. It is nothing new really. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
