Carmack on why transatlantic ping is faster than pushing a pixel to the screen
LOL I used to own a computer game center and had two dedicated T1's bonded and traffic managed.  The CS players would complain if the ping time spiked from 20ms to 25ms to a server and would say it was causing them to miss shots. I reviewed the connections for jitter and all sorts of things and they would never believe that the 5ms didn't make the difference.To prove the point I downloaded a simple javascript stoplight app that would measure reaction time and told them if anyone could beat my times I'd give them an all day pass.  And it never happened.. not even once.. and the times were lucky to be in the 210+ms range.  5ms wasn't causing them to miss the shot..For those who are interested:http://getyourwebsitehere.com/jswb/rttest01.html
