Hello,
Please follow this article – https://xstore.helpscoutdocs.com/article/100-how-to-speed-up-my-website Provide temporary wp-admin and FTP access, so we can take a closer look. https://gyazo.com/6e1a695554c51bdf97e196b97c9bb486 – all these issues are related to server settings and to your content. Not to theme settings. So, contact your hosting provider to get help with this. https://wpastra.com/add-expires-headers/ https://kinsta.com/blog/make-fewer-http-requests/ https://wpengine.com/resources/how-to-enable-gzip-compression-for-wordpress/
