The way in which P::RD is implemented gives it great flexability and power. But this comes at the cost of performance.

If speed is of a real concern then I would suggest you look at byacc and the perl output mode. Although you will still need to write your own lexer.

This is what I have done in the past, and can bee seen in the parser included in Convert::ASN1
