Upgrade! 486 motherboards with CPU are so cheap that there is no

It runs 25% faster on my P-90 (it's mostly I/O bound), but I'm not
complaining. It might be possible to tweak the translation a bit
more.
You might try also mawk instead of gawk. gawk is slow. Running the
script with mawk was 36% faster than gawk.
Defaulting to the perl version is probably better since most people
don't have mawk.
