TCP connection at hundreds of, the response time of the test is very long.packet Capture analysis, the original is three handshake SYN packet server is not timely response, resulting in SYN retransmission (3 seconds later, 9 seconds later). If the SYN is lost, it will be re-sent, but the first time is 3 seconds, the 2nd time is after 9 seconds, if the Syn_ack received after the re-send, it causes the TCP connection is very long,This results in extended business response times. 4) Response tim
