CPU utilization measure impacts on throughput?

Hi, everyone,

I have experienced that we got different throughput numbers in the
TCP_STREAM test where we measured CPU utilization (with -c & -C options)
as well as throughput measurements vs.. the another TCP_STREAM test
where no CPU utilization measurement (without -c nor -C options).
Usually throughputs of the test without CPU utilization measurements are

Does the measurement of CPU utilization (negatively) impact on
throughput measurement?
