Well... TCP handshake will take much longer (>~ 10ms, if I got the 0s right at the top of my head), and you can't cut anything off that time (1.8e12 furlongs per fortnight, or 3e8 m/s, etc). And then it's between TCP slow start and your link's bandwith (they come in all kinds of speeds these days). Calculate and test...
