I can't find the explanation on why noexcept could hurt performance. One reason I can see itt is some containers like unordered_map can inline the hash along with the key with noexcept, which may not worth additional memory overhead if the hashing is relatively cheap. He talks a bit about it in "Intel+Windows+MSVC" but not much info. I wish there was

noexcept helps in some cases that author doesn't seem to be using and any performance gain or loss is basically due to some (unrelated?) optimization decisions the compiler takes differently in noexcept builds if I am understanding correctly?
