Hi<br>
Looking into the following blueprint which requires that network<br>
performance tests be done as part of a scenario<br>
I plan to implement this using iperf and basically a scenario which<br>
includes a client/server VM pair<br>

My experience with netperf over the years has taught me that when there is just the single stream and pair of "systems" one won't actually know if the performance was limited by inbound, or outbound.  That is why the likes of<br>

apart from being poorly written python :)  Will launch several instances of a given flavor and then run aggregate tests on the Instance Under Test.  Those aggregate tests will include inbound, outbound, bidirectional, aggregate small packet and then a latency test.<br>

happy benchmarking,<br>
