That varies based on processor. The bigger the processor the smaller load the timer code puts on it. On a G5 I saw about .3% CPU Utilization from an idle machine without the patch. On a z800 it drops to about .1%. On a z900 it is probably negligible. But 100 machines on a z900 without the timer patch would be measurable.
