Nice. It would be interesting to throw in some even older systems. One that comes to mind is PLATO. I don't remember exactly what it delivered for response time, there were good test results on it. Somewhere in the 100 ms range, I believe, much of which was transmission delays due to low baud rates. And that was with 600 users, sharing a quad processor 4 x 10 MHz machine, in 1976.
