You need to apply the other 2 network context patches from the reviews I sent out

Sorry there was  typo in the patch should be @validation and not @(validation
Please change that in vm_perf.py

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

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

http://www.netperf.org/svn/netperf2/trunk/doc/examples/netperf_by_flavor.py

and

http://www.netperf.org/svn/netperf2/trunk/doc/examples/netperf_by_quantum.py

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.

happy benchmarking,

rick jones
