say,

if the seconds scheduled in sleep is 1 second
and the loop-iteration runs for 1 second

and there are some valid 10,000 loop-iteration in the code

then the processor has to switch from running state to sleep state for every 1 second and back to running state from the sleep state ... that in turn is a indirect load on the CPU ( a kind of bottleneck ) (switching from one state of a process to another state )

a direct inclusion of sleep as a means of reducing the load would not help all the programs.. i believe some thorough analysis has to be made ... to check for the exact bottleneck point

Well, i agree with you Matrix, it depends highly on the design and a (misplaced) sleep() will get things even worse Smilie
