Julia is designed primarily for numeric computation, but unlike a lot of other "math languages" like Octave, R, and Matlab whose general programming constructs are horribly slow, the overall general-purpose machinery of Julia (function calls, looping, data structures, dispatch, etc.) is said to be quite fast. Speaking of numeric computation, it is, in my opinion, a real weak point of Clojure. There is a huge perf. penalty for boxed numbers, and since anything in a Clojure data structure gets boxed, it's rather difficult to work around Clojure's poor numeric performance for anything more algorithmically complicated than a super-simple loop. A number of dynamic languages use tagged numbers (primitive types with a couple bits set aside to mark the type of the number), and these are going to do much better than Clojure for a wide variety of math-oriented computational tasks. I've benchmarked some specific programs in Clojure vs Racket and Racket tended to come out ahead when there was a lot of arithmetic. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
