Even if the raw CPU speed of Java is slightly less than C++, it is highly possible that the Java version runs faster compared to C++ version if a reasonably complex program if written both in C++ and Java. Java/JVM has some advantages. * Since Java supports garbage collection, objects can be passed across libraries without worrying about who should free it. Many times in C++, unnecessary copies are made at library boundaries. * JVM does memory compaction to avoid memory defragmentation. In C++, you have to live with it. memory fragmentation might also mean more cache misses and more page faults. * It is possible that JVM can move objects around for better cache accessibility. (I'm not sure if JVM does it, but it is certainly possible).
