The frame at 2:37 shows avg response time of 1.75 ms at 10 mln QPS. Which API call was measured? I'm looking at bar charts under "Metrics from Kubernetes 1.2" and the latencies graphed there appear to be different/higher.

"Metrics from Kubernetes 1.2" is discussing the latency of requests to the Kubernetes API (for managing what's in the cluster).

The latency referred to in the demo is the latency of requests from the loadbots to the nginx containers running in the cluster.

That's the nginx response time. You can see that when he scales up the loadbots but not the backends and says that the "tail latency has gotten quite high" (about 1min in).

Correct. In addition, the source code used to run the demo is available on github at https://github.com/kubernetes/contrib/tree/master/scale-demo

Thanks, all clear now.
