Hello, I just have a look at your code. I was wondering why reflect.Array/getDouble was faster than aget? And I realized than you create arrays of objects and not array of doubles.
Have you tried to replace make-array by double-array? I am not a Java specialist but if I understand well the API ot should create an array of unboxed doubles, making acces really faster. (No creation of Object when you write, nor indirection when you read). For access, I would use (double (aget ...)). But I am not sure. Can a clojure expert tell whether there is something like aget-double or another way to do it? You can also try to replace the arithmetic by unchecked arithmetic. (Is it correct from the point of view of the semantic of the VM you are implementing?). Can you try to check in your profiling whether the function you generate get compiled or not? What function are you running at the top level? Is that a loop where you run multiple times the same program?
