Hello, @Kstb1979,
I have checked your site score and check the results here: https://gtmetrix.com/reports/www.mysakhie.com/h9VFV1P7/ as you can see things are not very well maintained and there are some other things that need to optimize check here: https://postimg.cc/30gQ8jXb I marked the things that need to optimize so that you will never face any issue regarding the “Core vitals and speed score” For this you can use WP Rocket plugin it is most famous plugin also the major sites to check the speed of site recommend it. The plugin is compatible with our theme also, 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
