The 10 Mbps Thin Ethernet setting is a popular broadeband cable modem speed. If you have Verizon FIOS, your speed could approach 44.736 Mbps T3/DS3. Unfortunately, many U.S. users have much slower broadband speeds, more like 768 Kbps or lower.

Your actual transfer speeds will likely be a bit slower than the calculator shows. Why? Because on a normal Internet connection your transfer speed is decreased by:

  • The quality of the line and your connection to the the Internet specifically you can read up on the influence of latency and jitter.
  • There’s certain amount of your bandwidth used by your modem and ISP in just in keeping the line open! This background use known as “physical signaling overhead” isn’t available to you during your transfer. For example, the advertised transfer speed of a T1 line is 1,536 Kbps however 192 Kbps is usually tied up in the T1 line signaling protocol so the best you’ll ever get is 1,344 Kbps.
  • But wait, there’s more background use! There’s Layer 4 transport and transmission protocol maintainence/overhead. Amazingly, these below processes can eat up to 10% of your transfer speed. Handshaking negotiation procedures between you and the place you are transferring the file such as “slow start” described technically in RFC 2001. TCP overhead, error checking and sending of protocol header(e.g. Each IPv4 header is 160 bits, each UDP header is 64 bits, etc.)
