I'm sure the author is aware, but awk has at least three implementations: nawk (the one true), gawk (what most are using), and mawk (performance-oriented, unmaintained). Plus busybox-awk. When benchmarking gawk, I've found using LANG=C and avoiding UTF-8 to make a substantial difference for pattern matching.
