Trust neither. The most optimal option I've found is webpagetest.org Its been quite handy lately. This tool does look interesting. Source: about 1 year ago

Webpagetest.org is another. Pagespeedinsights and lighthouse are great for identifying page load issues to fix, but actual page load times will always vary between the user and your web server. Universal analytics has some page load timings but that's going away soon and nothing afaik is in GA4. I've seen an example of building a page load timer in tag manager and dumping the results into an event. Source: over 1 year ago

Academia.edu, researchgate.net, surprising amount of stuff out there. Hopefully you have. A library or institution to help you gain access if PDF not freely available. Source: about 1 year ago

Also, their assertions about publications are kinda hinky. I note that the "published articles" they cite are all links to researchgate.net rather than the actual journals, and the one DOI I tried didn't work, for a paper supposedly published in January. Google Scholar also has no record of that paper (Fossils on Mars? A “Cambrian Explosion” and “Burgess Shale” in Gale Crater?) other than the researchgate link. Source: over 1 year ago

So I looked around and pubmed didn't offer anything interesting though I found something on researchgate.net. Source: over 1 year ago
