I cannot believe that Which directory hierarchy will be the best/fastest? just got closed as "duplicate" of Can you help me with my capacity planning?. I hope the reason is not that the moderator has written the highest ranking answer to the question...

The questioner has asked a specific question, not broad like the other one. And I cannot see how the answers of the first question are of any use to the questioner (except for "use benchmarks").

I admit I am not really neutral as I just had put a lot of effort in answering the new question.
