Not really, comments like this are often wrong or misleading. After all, the programmer hasn't actually tested anything, they're just making assumptions. Otherwise they'd have actually fixed it. It's just pointless noise. A profiler will tell you that a particular function was run 10,000 times costing 0.5ms per run. You're not going to have a problem tracking down the problem, the comment won't help.
