Okay I got one really bad question which I can't delete because it has an answer and keep getting downvotes :(
I do not think it's a bad question. The man simply doesn't tell. It may be more appropriate for linux forum rather than server fault.
Also this is a question and answer site. I got one question merged. Yea IOtop is already explained in the previous question but it doesn't tell anything.
What should I do?
Is this because I asked too many questions?
