Slide 7 of 45
Notes:
R**2 ~ 0.6 i.e. 60% of the GET response can be explained by the ping response. More importantly there is a a lower limit around y=2*x. This is related to the GET taking 2 round trips (SYN/ACK & GET/response) versusPing taking a single round trip. The lower limit shows that given the minimum ping response one can get an idea of the best possible Web response.
