each keystroke has to be sent to Redwood City to be individually massaged and returned Is it an older terminal-based system? Lots of those were designed (and still in use, 40+ years later). Usually it's not a big deal, in fact faster than modern interfaces, because they're built for decades-old hardware and low baud rates. Of course if you're still running the original hardware or have really screwed things up then performance goes out the window.
