Pinned topic CPU throughput measurement

‏2013-10-22T16:49:56Z |

Just completed upgrade of p770 from MMB (3500 Mhz) to MMD (4228 Mhz).  I need to show that the MMD processes more work in a period of time as a result of the faster cpu clock speed. 

Using nstress (ncpu) I can make the system run 100% cpu utilization but is there a way I can count the number of instructions that were executed in the amount of time that ncpu was running?

    You can get those information from hpmstat, hpmcount  commands.
