Hi Everyone,

Can anyone explain me whats the difference between google page speed insight and avg loading time speed.
How these two are interconnected but in GT metrix my web page speed A but loading time 6.7 sec and in google analytics avg page speed is 4.5 sec.
and in google page speed insight its mobile speed - 64 and desktop- 83 something.

Real-World Field Data

When PSI is given a URL, it will look it up in the Chrome User Experience Report (CrUX) dataset. If available, PSI reports the First Contentful Paint (FCP) and the First Input Delay (FID) metric data for the origin and potentially the specific page URL.

Here's the difference: GT Metrix and other page speed test websites perform a real-time test, and usually this test is influenced on your site's server location, bandwidth, the speed website's server usage, etc.

Whereas Google's Insights uses real-world data of your real users who visit your website via Chrome.

In other words, the closest thing to real page speed statistics is Google.

Our dude is correct, other sites provide a real-time test (however GT does actually cahce - trust me, check in the morning, and then in the afternoon; it's a cached API). Google PageSpeed Insights & Mobile Compatibility are friends (they have a minimal cache and function of G's f'ed Chromium API). However, the cache lesser-so than our bois at pagespeed or gtmetrix (due to server space, and colo-memory).

Honestly: take every resource and then average the result... then look on each primary (non-third-party-caching) browser; then you will determine your actual time.

----------------------------

Otherwise: push it into your Chrome, count the seconds (pray no 3p-API got blocked (like Safari or other Chromium's did in '15) because that's f' you). If this happens PM me... and I will show you how to re-mediate it via wed.cofig or .htaccess.
