First of all, Please check your site speed score: https://postimg.cc/VdvtfbHW
Now, the point is how do we overcome your issue? The thing is once we import the default demo content of the theme it is already optimized so the user doesn’t need to maintain the site speed. But when a customer starts building the site and changes the demo content with his/her content, if the content the user upload on the site is not optimized and the customer uses multiple third-party plugins on their site it affects the site speed, and the user needs to optimize the speed of the site again.
To optimize the site speed user can do it manually, It takes a lot of effort and customization but on WordPress, there are many plugins available for this. So if you check my previous reply I told you about the WP Rocket plugin “Check here the documentation to learn how the plugin works with our theme: https://xstore.helpscoutdocs.com/article/128-how-to-improve-wp-rocket-settings-with-xstore” it helps to optimize the site speed. Also, I shared an article on it for a better reference to understand how you can use it with our theme to solve your site speed issue.
When we use a multipurpose theme try to avoid using third-party plugins as much as possible, remove all the unnecessary and draft pages, plugins, products, posts, etc from the site using a CDN, with a lightspeed server, and a cache plugin all these techniques will help you to optimize the site speed on mobile and desktop.
