You&#39;ve been asking the same thing for days, but each time your question is minimal, gives very little information and that&#39;s why you get few replies, and the replies you have received you&#39;ve just ignored and asked the same question again.</p> <p>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.</p> <p>And stop posting this same question until you are prepared to write a proper question which people can answer.</p><div style="clear:both;"></div>
