The relative efficiency between two detectors is a measure of the amount of data one detector requires, relative to the other detector, to attain a prescribed level of performance. In this paper the behavior of the relative efficiencies of two pairs of popular detection systems is investigated, and it is shown that the commonly employed asymptotic value of the relative efficiency can sometimes be a poor indicator of finite-sample-size detection performance even for some very large sample sizes.
