I've been trying for the last couple of days to improve the performance of our Wordpress site for mobile usage. In order to validate the optimisation process, I've been using PageSpeed Insight and Lighthouse (mobile).
As you can see in the first picture, everything was green, but we were at the 2.5s limit for the LCP, so we wanted to optimise more. In order to quickly test various tweaks, I switched to Lighthouse in my browser (incognito mode, no extensions).
You can see the results in the second picture. The results are similar, but a bit more discouraging. So I wanted to check the Original Trace of this Lighthouse run to understand what is leading to 3.0s loading time for LCP.
As you can see in the third picture, surprisingly, the LCP seems to load at about 470-500ms. That is at least 5 times faster than what the Lighthouse benchmark reports. Moreover, the entire page seems to load in less than 1s.
So my question is where is this difference coming from? Why are Lighthouse and PageSpeed Insight reporting different values than the actual Performance trace.
Thank you!
