What is written is very correct. I just saw that milli and microseconds are used in the same sentence. But I did not read it carefully enough. It takes 2.7 microseconds per rule (there are 1000) which, when a packet has to pass through all rules, makes 2.7 microseconds * 1000 = 2.7 millisecnds per packet. So I was wrong.
