Speed is not the issue, it's IO. Also streaming 100Gbps of video is very
different to streaming 100Gbps of files smaller than 100kb (average of
about 30kb) the issue on the network level is the number of connections and
CPU, on the server side it's IO and FSB

The trick is to realize that 100Gbps of files smaller than 100kb can be remodeled
as 12 Gigabytes/sec of random 128K writes into large files.

Which isn't even that hard with modern gear, especially if you have the budget
for SSDs.
