This is surprising to me. I would expect especially ints to be faster. In reality, there is no difference between arr ~= args and arr.length += args.length, and then copying, it's just how you do the copying. Perhaps it's the call to memcpy in the runtime that is slower than looping.
I think it's compile time looping, it's unrolled.
Did you compile both tests with the same command line parameters?
Yes.
