Indeed, mawk is slightly faster than gawk. The mawk variant is occasionally mentioned in comp.lang.awk. It is available in the Debian repositories, so I often have it available, but I rarely install it in other distributions that I have in (testing installs on) virtual machines. For example, it s not present in the standard repositories for openSUSE 11.2 "Emerald".
Both claim to be standard compliant, although the exact phrase for gawk is " ... almost completely POSIX 1003.2 compliant ..."
Here are the versions and timings for one run against a 12 MB file that has "fiber" only at the very end of the file, and "alpha" does not occur at all -- using the techniques discussed earlier:
