If we:
1) Count bytes/bits at the network adapter level (raw # of bits through the NIC) and,
2) Count bytes in all HTTP/S request/responses.
Assuming only HTTP/S traffic is on the box, and assuming a statistically relevant amount of "typical" web traffic:
I want to know about how much more traffic will be counted at the NIC level than at the HTTP/S level (counting http headers and all) because of the extra network overhead.
