While you're certainly right about DrRacket introducing noise in performance measurement, I don't think you need to generate an executable to eliminate that overhead. Simply running `racket` from the command line on a file in a module ought to be sufficient. Sam ____________________ Racket Users list: http://lists.racket-lang.org/users
