Google PageSpeed Insight is optimized

We already use Google PageSpeed Insights Tool for checking the page load speed of our website. It is now optimized to use real-user data from Chrome to display how optimized your site actually is. So if you still have poor page load speed, try improving it now!

I think if still you have poor page load speed then have to consider such things like CSS, JS. I mean try to keep number of CSS and JS files as less as possible. Use minified CS and JS file. Use properly optimized images. Try to include all JS code at the bottom of the page such that page loading speed may not be hampered.

Seems like Google is delivering more of 'real' data based on user experiences with a particular website.

You should perform the website optimization techniques to improve the speed of website. You should optimize the images, databases, scripts. Because website loading depend on how heavy is your website that how much time images, databases, scripts are taking to load.

You can also make sure that there should be minimum redirection applied for the site. One more point is, server uptime and response speed. Your server should be maintained properly so server uptime will remain consistent and site will load properly.
