stop asking the same question over and over again. You've been asking the same thing for days, but each time your question is minimal, gives very little information and that's why you get few replies, and the replies you have received you've just ignored and asked the same question again.
There is a HUGE search feature up there ^^^^ on the page which has lots and lots of previous (proper) posts about throughput and how to maximise it - try reading some.
And stop posting this same question until you are prepared to write a proper question which people can answer.
