JIT
64 bit JIT and 32 bit JIT are 2 very different beasts which is what one would suspect. But still I was rather surprised that 64 bit JIT was able to reduce the call stack of a call by 20% in comparison with 32 bit JIT. A piece of my code crawls the call stack to gather some runtime characteristics and it broke on a 64 bit machine. That's how I started a small investigation and found this difference. In most cases it's not a good idea to rely on the way JIT works as this is subject to change...
