Hello, @suneye1982,
I have checked your site theme settings and set as recommended. Now, to optimize the site speed there are a few necessary things:
“Eliminate render-blocking resources” For this, Please disable the third-party plugin first that you are using for checkout “Checkout Field Editor for WooCommerce (Pro), Cherry WooCommerce Package, Enter with the mobile number, TeraWallet, and WooCommerce Product Variations Swatches”
Second, You are using the WP Rocket plugin on your site. You have to set the settings of this plugin as recommended. Please check this article it helps you to understand: https://xstore.helpscoutdocs.com/article/128-how-to-improve-wp-rocket-settings-with-xstore
Once you disable the plugins and set the plugin settings please check the site speed again. For now, it is “48%” with a load time “6.1s” it will be improved and you will get the desired results: https://postimg.cc/Lg44nsWK
