However, the real problem is that if you have to travel outside of your local (Comcast) metropolitan network, let alone out of state to connect to a trading/quote server that is on opposite ends of the country, your speed will not be anywhere near what it is on your "local" network.
For example, I get 7.5 mb's on the download from LA to San Francisco.
But going outside of the local Comcast network to Chicago sees my speed drop to 6.0 mb's . . . and to NYC I am down to 5.1 mb's.
At least my trace-routes back East average around 88ms, which is actually fairly good.
