But aren't those two completely different cases (even if it is the same instruction)? The first is an unconditional branch, the second one a conditional branch. That probably makes a big difference to the processor. Where I expect the unconditional one to be faster than the conditional one. I assume it is 43% faster than the conditional one? If it is the other way around I will be very surprised as well.
