Hi all,

I have collected system samples using oprofile for period of 2 minutes. My system is pentium 4, 2GHz. For events like CPU UNHALTED CYCLES, I used a event count as 10,000.  No of samples i gathered during 2 minutes execution is x. Hence, total cycles consumed in this profiling is 10,000*x

once cycle in my system takes (1/2Ghz) second

So, total time should be 10,000 *x * (1/2Ghz) second. Unfortunately, I am not getting 2 minutes as execution time. Am i doing anything wrong

Thanks in advance
-John
