The majority of the time in the original version was definitely being spent on string-split (and I confirmed that regexp-split is basically the same, even with bytestrings). I found a post about regexp-split being dreadfully slow for a big string and a tiny pattern that Matt Flatt fixed a long while ago. This might be a similar edge case? big string, tiny pattern, but tons of matches? ____________________ Racket Users list: http://lists.racket-lang.org/users
