Hi ,
I ran perfmon with and without long sampling periods and got the
following result.
With long sampling periods pfmon reported
18,446,744,073,709,537,715 INSTRUCTIONS_RETIRED
Without sampling,
436,652 INSTRUCTIONS_RETIRED
I don't know what I have done incorrectly. Am I interpreting the
numbers incorrectly? Detailed command line and output is below. This
is on a Nehalem processor.
