Veydan, the clock you are talking about refers to the global system clock. The CPU clock setting that you noticed in fs.py is the CPU clock. The global system clock is fast so that you can have clocks of other components in the system (busses, etc.) set relative to the global clock at a fine granularity.

I don't want the CPU run so fast. Besides, > in the fs.py, the CPU is set to 1GHZ, what about this?
