The CIF 3 simulator has a Profiling option (Simulator category). If the option is enabled, information about the number of transitions taken per second, is printed to the console. Enabling profiling disables most other types of console output. By default, profiling is disabled.

The profiling output looks somewhat like this:

750431.42 transitions/second
640589.87 transitions/second
890939.01 transitions/second
887228.57 transitions/second
890143.25 transitions/second
893674.44 transitions/second
891812.69 transitions/second
