HyperRez:  Speed                                <sum08 1 7>
================

        One common first impression of HyperRez is its speed, especially when
        running the program on a hard disk.  Here's why HyperRez is fast:

        (1)  Files are ASCII -- HyperRez uses ASCII files <link16> that load
                                much faster than graphic files of competitors.

        (2)  Files are small -- While HyperRez can load ASCII files up to 20K,
                                most files are single screen (average size 2k).

        (3)  Total file load -- HyperRez loads the entire ASCII file into a
                                buffer so page jumps <link06> are instantaneous.

        (4)  Perceived speed -- Software quality is often measured by the speed
                                of screen updates.  If command response is
                                greater than 1/10 of a second, the mind
                                wanders, hampering users  <link34 1 22>.

        (5)  Browsing effort -- Browsing uses experimental exploration as a
                                primary method of search.  As a mental process,
                                browsing only works if the hypertext jumps are
                                intuitive and instantaneous <link32 2 10>.
