Refer to your Xena documentation to understand the behavior changes in modifying these values. +Xena RFC2544 testing inside VSPerf also includes a final verification option. +This option allows for a faster binary search with a longer final verification +of the binary search result. This feature can be enabled in the configuration +files as well as the length of the final verification in seconds. + +..code-block:: python + + TRAFFICGEN_XENA_RFC2544_VERIFY = False + TRAFFICGEN_XENA_RFC2544_VERIFY_DURATION = 120 + +If the final verification does not pass the test with the lossrate specified +it will continue the binary search from its previous point. If the smart search +option is enabled the search will continue by taking the current pass rate minus +the minimum and divided by 2.
