Reminds me, I had to once set up lighthouse scans for thousands of sites and the only way to do this fast enough was to run the tests concurrently on a single machine. But the test results also depended on cpu load of thr machine running the tests, so we had to sample cpu load live and adjust a multiplier in the lighthouse tests to handle this so that lighthouse would not think it is the site that is being slow. I understand it’s a complex tool, but I wish lighthouse results with the cli were more reproducible!
