Hello, Jalal,
Thank you for contacting us and for using XStore.
1/ Please follow this article – https://www.8theme.com/documentation/xstore/troubleshooting/how-to-speed-up-my-website/

– Reduce initial server response time – contact your hosting provider, because it is server-side.
– Avoid chaining critical requests – https://wp-rocket.me/google-core-web-vitals-wordpress/avoid-chaining-critical-requests/
– Use a Content Delivery Network (CDN): CDNs can give an equally fast web experience to your users across the globe. You can reach out to your hosting provider on this.
– Serve static assets with an efficient cache policy: A long cache lifetime can speed up repeat visits to your page. You can consider the WP Rocket plugin for it.
– Avoid long main-thread tasks – https://gtmetrix.com/avoid-long-main-thread-tasks.html
2/ Go to XStore > Patcher > Apply all patches.
Kind Regards,
8theme team
