The input file matters
With an input file, similar to your Moby Dick and not directly related to the problem at hand in this thread (and with which there were no matches) I also get a factor 5 difference between gawk and mawk, so your result may be a compile thing?. The difference between cgrep and mawk is a factor 6.
With an input file that is a large version of the input file of the problem in this thread, mawk and cgrep are about the same speed, with mawk being 5-10% faster than cgrep, while the difference between mawk and gawk was still a factor 5 - 5.5

igawk
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
