This could not possibly be further from the truth. Getting rid of heap allocations can speed something up by ~7x. Cache locality can speed something up by 50x. Compiler optimizations do very little compared to accessing memory in a predictable way.

Indeed! In Java or dynamic langauges you are forced to always use a reference. Which means you'll get cache misses pretty much everywhere.
