The code I checked was the version posted, which did not inline subs. Obviously, inlining subs will speed up all the versions.

My version averages about 27 seconds for a million strings on my computer which is a fairly low-powered netbook, several years old. Versus Re^3: Fast - Compact That String which averaged about 30 seconds for a million strings, on the same computer.

Scripts I tested, including input data are available at http://buzzword.org.uk/2012/faster/.
