memdecay - memory decay measurements 1) for anonymous memory, 2)
for cached memory from existing files, and 3) for cached memory
from deleted files.

See memdecay.1 manual page for detailed documentation.

See "doit" file for a trivial shell script that can run continuously
in the background to collect memory decay statistics. Run as:

    # sh doit >filename &

This runs memdecay repeatedly and collects all output in the named
file. You can watch progress with tail -f if you like.

Changes over the initial memdecay version: minimal (100) and maximal
(1000) number of memory samples per measurement, so that we can
compute and plot averages of multiple memdecay runs.

Analysis scripts (both need gnuplot):

plot-average100.pl filename

    plot averages of memdecay results in the named file, result is
    filename.average100.pbm.

plot-multi100.pl filename

    plot one graph with all individual memdecay results in the
    named file, result is filename.multi100.pbm.
