You've posted the same question four times and not got an answer - perhaps because it is difficult to reply without appearing rude. The bottom line is that if you understood what a performance operator does then you would not have asked your question even once. If you go through the samples it is almost impossible to avoid performance operators, and you have already been advised you to examine the samples, by me, here...
