interperting vcpuperf results — Vertica Forum

interperting vcpuperf results

I'm having some trouble interperting the vcpu results on a machine. Initially I found these results:

This machine's time:

  CPU Time: 9.130000s

  Real Time: 9.130000s

  This machine's high load time: 65 microseconds.

  This machine's low load time: 238 microseconds.

 

This clearly indicates some throttling so I disabled the OS power management and set the BIOS to max performance.  After doing so I get these results:

 

This machine's time:

  CPU Time: 10.430000s

  Real Time:10.430000s

  This machine's high load time: 128 microseconds.

  This machine's low load time: 129 microseconds.

 

Here's my question: after disabling throttling we've elminated the differential between high/low load times. However both high and low times are much greater than the 65 micro seconds we see initially. Is this normal to see both times greater than the high load time with power management enabled? Does it indicate I've lost some processing power?
