It would be fascinating if you could give any such comparison examples. The only time I've seen JVM come anywhere close to C++ in normal usage is if the C++ code was written like it was Java - that is, lots of shared_ptr heap allocations for nearly everything. Or perhaps you're one of the rare few that write Java code like it was C instead? You can definitely get something fast like that, but it seems all too rare.
