You DO know that script has been written in 1991, and computing power has increased by a factor of 2 every 18 months since then (according to Moore's Law). This means that (if I didn't use the wrong calculation formula) a loop that took 1 second then has to be run about 10000 times (give or take). The loops used in your benchmark finish so fast, that any calculation using the time expired (like line 38ff in your script) may as well use zero.
Use the input you have a few thousand times over, and you might get results, maybe even slightly meaningful ones. Or if it's just raw CPU power you're interested in, calculate Pi to a few thousand digits after the decimal point. That way, if you finish too fast, just add a few.

IGAWK(1) Utility Commands IGAWK(1)
NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
