To find the clock speed of a sun workstation

Hi Is there anyway of finding the clock speed of the CPU on a Sun workstation? As far as i know it can be found only by rebooting the machine and using module-info? And I believe that the module-info does a no-op loop for a a known number of times and calculates the time taken. I would like to know if there is anyother way to finding it. Thanks! Ashfaq
