I think normally you set a priority for the process (at least on Unix like systems), rather than specifying the % of CPU time -- this give fairer control, as if no one else is using the machine, your low priority task will use up the CPU cycles that will otherwise be idle anyway. On the other hand, if the processor is busy with higher priority task, then your low priority task will not be taking up the CPU cycles at all.... > 2) Is it possible to determine which predicate is called how often/how > many CPU time it uses ?

The timing profiler probably comes closest to your description, but note that this is not supported on Windows.
