  3. 5.How long did it take the client to issue the first GET for stream 0 after the TCP 3-way handshake was completed? Add in a screen shot of this with the HTTP expanded so you can see information about the GET.(4 points)
  4. 6.Is this fast or slow? NOTE:What is fast or slow is not specifically discussed in the material for the week.Is a response in some ten-thousandths of a second is seen as fast “enough” according to DeVry? What do you think? Justify your answer. (2 points)
