                                            As a rule, RTL code contains fewer instructions than stack-based instructions, and as result spends less time in interpreter instruction dispatch code. But RTL sometimes spends more time in operand decoding. More importantly, RTL code results in less memory traffic, because local variables and stack values are addressed directly by RTL instructions. Therefore, stack pushes and pops of local variab
