True,if you want to compared the performance of the Stein and Ocata, you

I think you can set the configuration item " vif_plugging_is_fatal=False" [1] 
in the nova-compute.conf, and
then compare the performance of Ocata and Stein version by creating the same
quantity servers. And you can combine with the configuration item "
vif_plugging_timeout" to use.
This way, you can verify if you are creating servers slow because of network.
