I did some testing: https://s3.amazonaws.com/synthetic-tests-result-wikimedia/firstView/2023-03-08-10-07-52/pages/en_wikipedia_org/wiki/Barack_Obama/metrics.html

The CPU benchmark score is 200 ms and the TTFB is 126 ms, lets sync that with what we see from our real users.

Peter mentioned this in T299886: Upgrade to Chrome 97 increased first visual change metrics for synthetic testing.Mar 8 2023, 12:13 PM

I've setup three URLS that we test once every hour and gonna let that run until tomorrow to just collect some the data. Then look at the CPU and TTFB and sync if they should be changed.

I added the same URLs to run with WebPageReplay, then tomorrow I will sync CPU benchmark/TTFB and document it so we can motivate how and why we run with the configuration.
