Maybe, you should try another lexer generator. as John mentioned,
flex is supposedly faster and re2c is supposedly even faster.
flex has the advantage of being mostly lex compatible, whereas re2c
would require a little more work. But there are other lexer generators
out there in case neither flex nor re2c suits you.
