We are currently running into an issue where several of our metrics have increased with no known changes to our site. We have an EC2 cluster of private instances based on the AWS AMI. That cluster failed at 10PM Eastern on 6/20. When it came back online, we noticed some new metrics in the reports (including Interactive on the waterfall). We also noticed the browser CPU time doubled and Time to Start Render and Visually Complete times went up about 20%. If we suspect wptagent updates are impacting our numbers, is there a way we can revert to a previous version or disable updates for testing?
Thanks,
JVO
