> I don’t think it’s relevant here, the JIT compiler can do the same optimizations here. Correct. I was clarifying that the issue can be replicated in a "simpler" statically compiled benchmark. > If the branch predictor can basically 100% guess correctly (which will be the case in any correct program), it should not have any additional cost That isn't true. The CPU branch predictor has a cost no-matter what. Of course, it's a complicated story: https://blog.cloudflare.com/branch-predictor |
