+a DUT application (e.g. VPP, DPDK), are determined by testing it in the
 same test environment, to avoid test environment changes clouding the
 picture.
+To beter distinguish impact of test environment changes,

 A mirror approach is introduced to determine benchmarking anomalies due
 to the test environment change. This is achieved by testing the same DUT
