I notice this code is using lists instead of vectors, this quite a performance hit, on my machine: (def my-vector (vec (range 0 1000))) (def my-list (apply list (range 0 1000)))
;; ~30ms (time (dotimes [x 1000000] (nth my-vector 999))) ;; ~9000ms (time (dotimes [x 1000000] (nth my-list 999))) On Wed, May 13, 2009 at 12:59 PM, Jeremy James <jja...@gmail.com> wrote: > > > > On Apr 24, 10:52 am, tmountain <tinymount...@gmail.com> wrote: > > Very cool.
