-
Roughly half of the packets in HTTP/1.0 are TCP open/close
-
Such packets are not "congestion controlled"
-
Significant further gain by using buffering with pipelining
-
Validation may use as little as 1/10 the packets of HTTP/1.0
-
Cache load may use less than 1/2 packets of HTTP/1.0
-
The mean size of a packet doubled in our tests
-
The mean number of packets in a TCP session increased between a factor
of 2 and 10. This is less than one might naively expect, and is due to
buffering that reduces the number of packets/session.
