I recently got clojure source and rebuilt clojure.jar. I noticed that the performance is significantly worse with the new clojure.jar compared to a older clojure.jar. Everything else is the same, I just change the clojure.jar file and the performance is 4x slower. Below the output - Note the runtimes. The application is just a solution finder to a solitaire type problem. Incidently, the equivalent solution in Clisp runs in < 10s.
