1) The command line requested for these first programs doesn't AOT compile so the measured time includes compiling the program. Perhaps AOT compilation is an usual way to use Clojure - or perhaps it would be better to show programs that used AOT compilation? http://groups.google.com/group/clojure/browse_thread/thread/e9902e30afbb805e 2) mandelbrot - There seems to be some problem with the mandelbrot program - the program doesn't seem to exit for perhaps a minute after the output file is created - see the difference between "CPU secs" and "Elapsed secs". http://shootout.alioth.debian.org/u32q/program.php?test=mandelbrot&lang=clojure&id=1 3) regexdna http://shootout.alioth.debian.org/u32q/program.php?test=regexdna&lang=clojure&id=1 -- You received this message because you are subscribed to the Google Groups "Clojure" group.
