I was able to successfully set up the example Headless Chrome demo on GAE Standard with the new runtime.

However, I'm seeing 10-40 second latency for screenshots (no changes to the code). In stackdriver, 6-9 seconds of the latency is due to the puppeteer.launch call. This is incredibly long.

Understand the new GAE Standard Node.js runtime is in Beta, logging to keep track of any updates as several projects will be enabled by usability here.
