Title: WP Fastest cache not compatible with Flying Scripts Plugin Last modified: September 23, 2022 --- # WP Fastest cache not compatible with Flying Scripts Plugin * [Amal K](https://wordpress.org/support/users/amalendukundu2013/) * (@amalendukundu2013) * [3 years, 8 months ago](https://wordpress.org/support/topic/wp-fastest-cache-not-compatible-with-flying-scripts-plugin/) * Hi, First of thanks for this wonderful plugin. I use your plugin in all my website. To achieve better Google CWV score, I am thinking to implement delaying JS load and there is nice plugin name ‘Flying Scripts’ ([https://wordpress.org/plugins/flying-scripts/](https://wordpress.org/plugins/flying-scripts/)) for this purpose. * I tried to use Flying Scripts with WPFC but it is not compatible some how. I have created a support ticket with them here: [https://wordpress.org/support/topic/compatible-issue-with-wp-fastest-cache-plugin/](https://wordpress.org/support/topic/compatible-issue-with-wp-fastest-cache-plugin/) * But the update is they said they can not fix it. * Could you please take look and either implement this functionality in your plugin or make your plugin compatible with Flying scripts. * I really appreciate your plugin and it is really really good. WPFC + delayed script will be deadly combination for page speed. * Regards, Amal * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fwp-fastest-cache-not-compatible-with-flying-scripts-plugin%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 8 replies - 1 through 8 (of 8 total) * Plugin Author [Emre Vona](https://wordpress.org/support/users/emrevona/) * (@emrevona) * [3 years, 8 months ago](https://wordpress.org/support/topic/wp-fastest-cache-not-compatible-with-flying-scripts-plugin/#post-16037731) * thank you so much. * I do not recommend you to use more than one optimization plugin concurrently. * Thread Starter [Amal K](https://wordpress.org/support/users/amalendukundu2013/) * (@amalendukundu2013) * [3 years, 8 months ago](https://wordpress.org/support/topic/wp-fastest-cache-not-compatible-with-flying-scripts-plugin/#post-16052028) * Thanks for the update. Will it be possible for you to include the feature of delay JS load like flying script in your plugin WPFC. * As I said earlier, it will be really good. In fact Deadly! 🙂 * Plugin Author [Emre Vona](https://wordpress.org/support/users/emrevona/) * (@emrevona) * [3 years, 8 months ago](https://wordpress.org/support/topic/wp-fastest-cache-not-compatible-with-flying-scripts-plugin/#post-16052605) * why do you need it? * Thread Starter [Amal K](https://wordpress.org/support/users/amalendukundu2013/) * (@amalendukundu2013) * [3 years, 8 months ago](https://wordpress.org/support/topic/wp-fastest-cache-not-compatible-with-flying-scripts-plugin/#post-16055288) * Sometimes third party scripts like chat or analytics or popup scripts cause impact on the CWV on Google pagespeed. Delay loading these JS which are not essential to load the page, can improve CWV scores. Flying script is one of the plugin which is really good and unfortunately it is not compatible with WPFC. * The feature of delay loading like after certain time (after few seconds) or when mouse move, helps improving CWV as for google these JS scripts does not load. - This reply was modified 3 years, 8 months ago by [Amal K](https://wordpress.org/support/users/amalendukundu2013/). * Plugin Author [Emre Vona](https://wordpress.org/support/users/emrevona/) * (@emrevona) * [3 years, 8 months ago](https://wordpress.org/support/topic/wp-fastest-cache-not-compatible-with-flying-scripts-plugin/#post-16055290) * are you talking about the “Render Blocking Js” warning? * Thread Starter [Amal K](https://wordpress.org/support/users/amalendukundu2013/) * (@amalendukundu2013) * [3 years, 8 months ago](https://wordpress.org/support/topic/wp-fastest-cache-not-compatible-with-flying-scripts-plugin/#post-16055378) * Hi, * No, I am talking about delay JS (not defer JS). Basically it is a lazy loading of JS scripts. In defer JS the script loads and contribute but to the total page load time but in delay JS the script loads after few secs or on mouse move events. * So when Lighthouse open the page, it does not see the delayed JS files thus the script execution time is considered low. * When the initial page loads, it does not load a JS script. It is loaded after few secs or if a mouse is moved. * Please check this Flying scripts: [https://wordpress.org/plugins/flying-scripts/](https://wordpress.org/plugins/flying-scripts/) Regards, Amal * Plugin Author [Emre Vona](https://wordpress.org/support/users/emrevona/) * (@emrevona) * [3 years, 8 months ago](https://wordpress.org/support/topic/wp-fastest-cache-not-compatible-with-flying-scripts-plugin/#post-16056254) * can you contact me via email please: [https://www.wpfastestcache.com/contact-us/](https://www.wpfastestcache.com/contact-us/) * Thread Starter [Amal K](https://wordpress.org/support/users/amalendukundu2013/) * (@amalendukundu2013) * [3 years, 6 months ago](https://wordpress.org/support/topic/wp-fastest-cache-not-compatible-with-flying-scripts-plugin/#post-16257607) * As I have checked with both the support from ‘Flying Scripts’ and ‘WPFastest Cache’ plugin (WPFC), but could not have a solution. * This message is for the people looking for an similar delayed script concept and compatibility with WPFC. * [Optimize More!](https://wordpress.org/plugins/optimize-more/) is the plugin I have tested and compatible with WPFC.
