That's unusual! Do you have enough experience to use the statistical profiler? If so, then sharing the profiling data will help. I think someone needs to run the code and profile. Nothing obvious comes to mind with regards to BSL and performance. ____________________ Racket Users list: http://lists.racket-lang.org/users
