I think you would also want to pay attention to how much control you need over memory allocation. Java doesn't give you much control over memory, yet in many scenarios (such as start-up time or running on devices) working set can be just as important as the actual codes executed for performance. You would have much more control over working set/memory if you used C/C++.
