    SubjectRe: Deprecating .gz format on kernel.org

    Among the latest 2.4-release kernels (2.4.19 and 2.4.20), it seems that
    bz2 saves ~6MB.

    Downloads: 1.5MB DSL

    time `ncftpget ftp://ftp.kernel.org/pub/linux/kernel/v2.4/linux-2.4.20.tar.gz`
    real 3m24.004s
    <snipped>

    time `ncftpget ftp://ftp.kernel.org/pub/linux/kernel/v2.4/linux-2.4.20.tar.bz2`
    real 2m51.481s
    <snipped>

    Uncompression: Dual AMD 1600+, 512MB ram, 30 GB seagate EIDE
    time `gunzip linux-2.4.20.tar.gz`
    real 0m5.428s
    user 0m2.285s
    sys 0m1.096s

    time `bunzip2 linux-2.4.20.tar.bz2 `
    real 0m28.892s
    user 0m27.318s
    sys 0m1.363s

    Compression: Dual AMD 1600+, 512MB ram, 30 GB seagate EIDE
    time `gzip linux-2.4.20.tar`
    real 0m18.771s
    user 0m17.990s
    sys 0m0.674s

    time `gzip -9 linux-2.4.20.tar`
    real 0m42.032s
    user 0m40.725s
    sys 0m0.791s

    time `bzip2 linux-2.4.20.tar`
    real 1m50.411s
    user 1m49.197s
    sys 0m0.555s

    bz2 is about 18% of the size of the tarfile. gz is 22%. gzip -9 saved a
    whopping 310k compared to gzip.
