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.
