Oh yes, there's still more room for optimization if you need it. If you can't get the speed you need out of pure Perl, you can also use Inline::C or XS for maximum speed. If the Pure perl solution is good enough though, I'd stick with that. I love benchmarking; results still find a way to surprise me.
