<pre>We don't usually spend a lot of time tuning for microbenchmarks, because such work doesn't end up benefiting real-world code. We only tune for microbenchmarks if the microbenchmark is carefully designed to emulate a VM pathology that occurred in real code.
I don't think that trying to optimize this tiny integer loop for cases where you didn't pass integers is going to have a high likelihood of helping users. I'd be more inclined to look at this if it was a bigger program.</pre>
