Need help to improve Page Load Time

[alien_]

- Host the website in the region where your users are, and test it from there with WPT as well.
- Use a CDN for static content and also try it for faster TCP connection setup that impacts the dynamic content TTFB.
- Check your backend's performance, perhaps it's waiting for something that could be cached there.
- Use DNS prefetching and preload from HTML the items that are needed for rendering the page
- defer loading of all the non-critical stuff
