What? Sorry, I genuinely have no idea what you're talking about. Is it possible to look at code and intuit, just by reading, how to speed it up? Duh, yes. If you disagree, lol.

Keep in mind that I've never stated that all performance issues are findable through code review. Just that there are many that are.

If you think that this is false, there's literally nothing you can contribute.
