The implementation of `+` with more than 2 arguments uses `reduce` internally. So they amount to the same thing. There isn't really a performance difference: user=> (dotimes [i 7] (time (reduce + (range 10000000)))) "Elapsed time: 354.475 msecs" "Elapsed time: 346.235 msecs" "Elapsed time: 348.124 msecs" "Elapsed time: 348.894 msecs" "Elapsed time: 379.9 msecs" "Elapsed time: 356.337 msecs" "Elapsed time: 362.788 msecs" nil user=> (dotimes [i 7] (time (apply + (range 10000000)))) "Elapsed time: 360.067 msecs" "Elapsed time: 353.281 msecs" "Elapsed time: 345.694 msecs" "Elapsed time: 355.162 msecs" "Elapsed time: 346.511 msecs" "Elapsed time: 350.61 msecs" "Elapsed time: 353.674 msecs" nil -- You received this message because you are subscribed to the Google Groups "Clojure" group.
