branch prediction stack overflow
In computer architecture, a branch predictor is a digital circuit that tries to guess which way a branch (e.g. an if-then-else structure) will go before this is known for ... , Interpreter overhead, and just being an interpreter, explains most of the average difference. I don't have an explanation for the higher variance.
