[Tutor] python, speed, game programming

[Keith Winston]

Just to be clear, what I'm asking this typing tutor to do is vastly more
than normal, albeit still not seemingly very much. In most programs, they
give you a sentence or paragraph to type, and then time how long it takes.
I'm talking about timing every keypress, and modifying the text stream
based on that. The thing that put me on edge was noticing that my simple
Chutes & Ladders game doesn't go ANY faster on a machine that benchmarks
perhaps 1000 times faster than another...
