In such a case, using a loopback tool will always yield the same results since the measurement will be affected by the lowest throughput, and test results will not show that one direction has higher performance than the other. The same scenario will occur if a network misconfiguration is present in only one direction of the service. Depending on the error, the problem will not be identified with round-trip measurements only.
