I'm still evaluating NFA9, and I was wondering if there was any point in applying netflow to 10Gb interfaces?

The reason I ask is because we have a mixture of 1Gb and 10Gb interfaces. The 10Gb interfaces are used as uplinks to our distribution switches. The utilization on the 10Gb will never reach peak utilization and therefore will not need NFA. 

Would that be correct?
