This is the same calculations as before, but with a different data set.
These are from a web server farm (a web portal), with the server farm
running on a single virtual IP address [*]. I have accumulated the
/proc/net/ip_conntracks from all servers in the farm. There are
37608 unique conntrack entries, and all but 2385 of them refer
to the virtual service IP and port 80. This dataset is to show
the extreme case of a single-address-and-port server.
