Can I ask what are the "costs associated with bandwidth metering"?

Can you explain how bypassing the caching proxy for large file downloads
enhances throughput or reduces bandwidth utilization?

I get the full Cable/DSL bandwidth for large file downloads via Squid:

1111285901.547 38678 192.168.0.252 TCP_MISS/200 15439237 GET
http://www.demography.state.mn.us/DownloadFiles/Profiles/cen00prof.pdf
- DIRECT/156.99.41.160 application/pdf

That's 15,439,237 bytes received in 38.6 seconds (3 megabits/second).
here is the same document served out of cache:

1111286373.206 2011 192.168.0.252 TCP_HIT/200 15439241 GET
http://www.demography.state.mn.us/DownloadFiles/Profiles/cen00prof.pdf
- NONE/- application/pdf

Yes, the cached reply is four bytes larger; the logged size includes all headers
(either way the saved file on the client comes out as 15,438,929 bytes).
