I have to admit that I haven't done many tests, but for those I did I found little to no difference, provided the tests have sufficiently long run times. However, what remains a problem for with the Java/HotSpot approach to performance is the absence of a clear (even though necessarily approximate) performance model. When writing C or C++ code, I have some idea of the approximate cost of everything. Of course there are differences between machines and compilers, but those rarely cause drastic differences in performance, rarely more than a factor of 2. On the JVM, I don't know what HotSpot can optimize and what it can't, and I can't predict the impact of object allocation and garbage collection. I suppose JVM experts can do better than me, but where can I learn about all that?
