On a lark, I ran a little script that re-compresses the components of a .deb with the desired compression program, and reports results: bzip2: Packages, total count: 22485 Originals, total size: 17467,4 MiB Repacked, total size: 15944,3 MiB Size reduction: 1523,06 MiB (8,7 %) Repacked bigger than original, count: 10777 lzma: Packages, total count: 22485 Originals, total size: 17467,4 MiB Repacked, total size: 13167,9 MiB Size reduction: 4299,46 MiB (24,6 %) Repacked bigger than original, count: 1421 The above are results for gutsy as of today (or as of about 24 hours ago, when I last updated my mirror). I chose gutsy, since it is a more stable target. Please excuse the use LANG=fi_FI formatting of numbers. Unfortunately, I didn't think of adding code to measure uncompression speeds. On the other hand, the machine I ran the script on is fairly fast, so it would not really care about the uncompression speed anyway. Such a test should be run on a slow machine. (If anyone wants to duplicate the test, I can provide the script, or the outputs of the script.) FWIW, I think it'd be a good thing for Ubuntu to switch from gzip to lzma. The space savings are quite significant. -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
