Re: Performance of calling primitive type hinted functions passed as arguments

The second one is slower because the (cb l) call is going via (fn [Object]) which then delegates to (fn [long]) rather than using (fn [Object]) directly. I believe it may be doing an extra cast as well, which would explain the extra 3ns of overhead. In general, I've found primitive functions ar

Re: Performance of calling primitive type hinted functions passed as arguments

I'm writing some low-level byte manipulation library and want it to be as efficient as possible, so I just want to know the cost of trivial things like this before designing the API. It can be negligible as you said, but I wanted to know why it is slow and what's happening under the hood anyway. O

Re: Performance of calling primitive type hinted functions passed as arguments

I am not convinced that this test is representative. If you are not using l but still hinting it's type, you may have extra code generated in the function body to handle the type hint. 4 milliseconds divided by a million is a very low overhead IMHO. I would hardly qualify this as being inefficient

Re: Performance of calling primitive type hinted functions passed as arguments

I'm taking a guess here: The compiler doesn't know the type signature of `cb` when compiling `foo`, so it's going to use the IFn.invoke(Object) signature. Clojure's type inference is only local, and it won't assume that a primitive-type signature is available for an arbitrary function. So there
