That's one I was using at the moment to have a quick test after
the reconciliation series was completed. It has since changed to
config-network-netperf-cstate-small-cross-socket to limit cstates, bind
the client and server to two local CPUs and using one buffer size. It
was necessary to get an ftrace function graph of the wakeup path that
was readable and not too noisy due to migrations, cpuidle exit costs etc.
