That's great to hear you approached this implementation. Even if it is 
simple multiplication it will be helpful.

Because we don't want too much CPU utilization on older machines and 
those which carry a lot of traffic

We just multiply with the sampling rate to estimate traffic. At this 
stage is acceptable.
