(...) Perhaps a good benchmark would be to write a PID controller and measure the number of control loop iterations per second that can be achieved under each environment. This incorporates sensor input with motor output, and uses a moderate amount (...) (18 years ago, 21-Jan-07, to lugnet.robotics)
