    Decompression speed test2: installer

    Test set: tar with TC UP 4.1, typical bloatware, a collection of programs that can do anything. I think that it's pretty representative to what installers do except for rather big size...which is needed to measure timing accurately.

    Data size: 261031424 B.
    Installer size: 94565574B.

    Tested on Pentium D 2.66 Ghz.
    * indicates the best modes, nothing beats them in both size and speed.

    (1) "The best" mode. Nothing beats it in both size and time
    (3) Global time, includes IO.
