Considerations on response time
zWAP1.x would take an advantage if content size were small, HTTP/TCP would take an advantage if content size were large.
y500byte(64kbps): WTP1.x is better than HTTP/TCP.
y100Kbyte(64kbps): HTTP/TCP is better than WAP1.x.
zReason
1.Because TCP slow start algorithm prevents making full use of network resources in the slow start phase, WTP is better than TCP in case of small contents.
2.WTP responder can send the number of packets based on the window size, but the WTP responder has to wait until the subsequent acknowledgement is received. That waiting time results in the increase of total response time.
3.TCP performance is better when transmitting large contents because dynamic flow control mechanism works well provided that the large size of buffer is prepared in the client.
