Well, I'd suggest you first measure the portion of the total amount
of runtime spent in the parser. Then you make an assessment of the
kind of speedup you can expect for the parser (e.g. you could measure
the Lua parser you use against a selection of parsers written in C).
Then you do the maths... =)
