I think the link is meant to be https://pagespeed.web.dev/report?url=https%3A%2F%2Fgoogle.co... - a perf report on the Google homepage. When I click the link from HN it pulls up a performance report on the performance report service (which is also bad.)
It's fascinating that according to the report, someone on a Moto G4 would have to wait over 6 seconds for the google search page to be responsive so they could type in a query.
