Hello,

We have checked your website and see that your home page is quite heavy and has a lot of unnecessary CSS and JS files. Most of them come with third-party plugins that are not related to our theme.

We recommend you disable these plugins and check the performance. Your home page slider you can replace with our theme’s slider https://xtemos.com/docs/basel/basel-slider/how-to-create-a-slider/

You can also try to use WP Rocket cache plugin to optimize your website.

Kind Regards
