Why page load time is different in google webmaster vs what is displayed in moz?

[etattva]

When I analyze the site through Moz tool and compare the results with google webmaster, I am not able to figure what why Moz does not report the slow pages.

Fro example this page has an avrage LCP of 3.0 sec https://www.collegehippo.com/graduate-school/programs/gre-score-business-analytics-data-analytics

When I see the report in moz, it does not point to any such issue.

Should I be worried about what google reports and try to fix the page?

Google is testing your pages using Lightspeed / Core Web vitals, or simply said https://developers.google.com/speed/pagespeed/insights/

The page speed testing done by MOZ is different then Lighthouse, because google actually relies on a real rendering scene rather then passively load everything together.

So if you want to get better scores to site speed, optimize using insights as the link above posted. Alot of gains can be made and the Time to first byte and actual rendering time could be improved massively.
