How to effectively optimize the loading speed (possibly reduce, lighten) The7 wordpress template?

Search Engine Optimization

Good day to all!

SSL via CloudFlare (Plan: Free Website, SSL: Full, Security Level: Medium, Caching Level: Standard, Development Mode: Disabled, joxi. ru/8236LKh6GG6bmO , joxi.ru/gmvnY9fxJJLxma, joxi.ru/GrqZY9INJJQvmz). CloudFlare WP plugin installed, activated and configured joxi.ru/n2YbdVSjddeJA6.
Caching plugin - W3 Total Cache (I would be very grateful if someone could reset the settings file of this plugin, given the above data, so that I can import them. Since, apparently, I have not been able to make friends with their settings yet).
At the same time, the main page is fully loaded in 9.26 seconds - see screenshot joxi.ru/DmBzM3QSN1Beym
Perhaps it is necessary to make it load in batches, such as text first, then styles, then everything else? If so, is there a guide on how to do this?
Thanks for any help as I haven't googled anything concrete yet. One of the main reasons for using it is the lack of experience in self-implementation and adding various functionality with code, and this theme allows me to customize a lot of things visually. The theme is visually very pleasing.

Answer 1

Use https://gtmetrix.com and https://developers.google.com/speed/pagespeed/insights/
They will show you that it takes a long time to load.
You need to optimize js, Autoptimize does a good job of this
