Have you read my answer to the question? I gave some hints what to change.

The answers to the canonical question do not add anything useful to the comment you made. Or do they in your opinion? If so: What? I would agree with you on "without benchmarks and a better idea of what's causing the slowdown I think it's pretty tough to give useful advice" (at least if "useful" is understood as "specific") but my impression of this site is that in such a case comments are used to get this information from the questioner and not that the question is closed, referring him to a thread that does not even cover this aspect.

@ChrisS This is not "capacity planning" vs. "performance planning". If that was the only difference then I would be with you. The questioner asks a very specific software question whereas the other question and their answers are both very broad and about hardware. The main point is: I don't see how the other answers help the questioner in any way.

@lain I did not intend to indicate that the mod wanted to get more reputation. I can understand that one's own answers are more on one's mind.

Wouldn't it be an easy solution to allow a configuration (if a user has e.g. 15K) that only those questions are visible to the user which have a positive voting (or at least +2, +3)?

Maybe this is just a technical problem? How about an option that you want to see only questions with an upvote result of x or higher? The questions who make certain experts angry due to the lazyness (or cluelessness) of the asker will not even get to two. This would even make upvotes more valuable: "Upvote a good question to make it reach a broader audience."

What do you mean by "graded"? Selecting as "this answer should be used for review tests"?
