This reminds me of the old saying "never under estimate the through-put of a station wagon full of hard drives". It looks like it has disappeared from the internet but at one time someone had a calculator where you could enter the number of hard drives your station wagon could hold, the size of the hard drives and the time it took to drive across town from data center A to data center B and would tell you what bandwidth you would need to transfer the same amount of data using FTP. I suppose you could make the same calculation if you could make the MTU size larger that the carrier pigeon was carrying.
