Murph,

The 50GB file (or any file) also has protocol overhead associated with it for error checking, acks/nacks, etc, right? What's this overhead? About 20%? If so, the times need to be boosted by the overhead amount.
By the way, that link points me to a search site.



Actually, for bulk transfers, there isn't much overhead at the protocol level. IP and TCP headers are only 40 bytes combined and you have 1460 bytes left for the cargo. Not to go off on a tangent, but the issue with file transfers over the internet really is about long fat networks. Plain ol' TCP simply cannot fill the pipe because the window size is too small. For anyone who wants to read up on it, read RFC 1323. I'm a network guy for a global financial company so this is my cup-o-tea (sorta speak)
