I think it was Jason and Matt who did this, not me. As John says, there is already some benefit from threading. By putting the UI and the simming stuff in separate threads, we make sure that the UI gets enough computing time to respond to our mouse clicks etc. I don't often run two instances of the Quackle UI, but in testing and generating stats I sometimes run two copies of Quackle on my MacBook at a command line, and the second one doesn't slow the first one down. So when we make the simulator multi-threaded so that it can sim on two or more processors in parallel, it should be about NumberOfProcessors times faster. John O'Laughlin
