The divider=<value> option is a kernel command line option that allows you to
adjust the system clock rate while maintaining the same visible HZ timing value
to user space applications.
Using the divider= option allows you to reduce CPU overhead and increase
efficiency at the cost of lowering the accuracy of timing operations and
profiling. This is useful when running RHEL-4 under virtualized environments to
help keep more accurate time and reduce load on the hypervisor.
Useful <values> for the standard 1000Hz clock are:
* 2 = 500Hz
* 4 = 250Hz
* 5 = 200Hz
* 8 = 125Hz
* 10 = 100Hz (value used by previous releases of Red Hat Enterprise Linux)
