    What kind of processor/system is that?

    I also see quite a difference in untarring gz vs. bz2.

    On a Pentium classic with genuine f00f bug, 180 Mhz, 80 MB of RAM,
    running Linux 2.5.64, I get:

    [rddunlap@eeyore linsrc]$ time tar xzf linux-2.5.65.tar.gz
    41.98user 38.15system 1:45.94elapsed 75%CPU (0avgtext+0avgdata 0maxresident)k

    [rddunlap@eeyore linsrc]$ mv linux-2.5.65 linux-2565

    [rddunlap@eeyore linsrc]$ time tar xjf linux-2.5.65.tar.bz2
