My backtracker makes 970 checks to fill an empty Sudoku board correctly, in about 30 microseconds.

Don't ask me how that CPU can do the check in 30 ns/check, but it does. The program has a single thread; before I started coding I was considering how to do multithreaded backtracking, but when a typical problem is solved in a handful milliseconds, then you don't do multithreading to improve response time. Actually, one reason why I would like a really difficult, time consuming one is to see if I can make it faster by multithreading.
