As the moderator who responded to your flag, it was correct. The original question did seem to ask for information on how to profile the application (off topic). However, I saw a good review question - performance is explicitly on topic. So I edited the title to ask for a performance review rather than a "how do I.." question.
Now, concerning the answers: I agree that the answers provided thus far don't really answer the question. That is cause for downvotes. My criteria for "Not an answer" is that the answer does not provide a solution, i.e., asks a question which should be in a comment or is merely a useless linky answer. Both of these I will convert to comments if I see them or respond to a flag. If I judge the link is irrelevant (not necessarily spam, but completely irrelevant to the question) I may delete it outright. Generally I err toward comment conversion.
tl;dr: You are correct; the current answers don't really answer the question. They should be downvoted. If more attention to the question is needed, a bounty could be posted or the question could be edited to be more specific, which would bump it to the top of the front page.
