Title: Plugin Increases Server Load Time Last modified: December 31, 2020 --- # Plugin Increases Server Load Time * Resolved [deborah86](https://wordpress.org/support/users/deborah86/) * (@deborah86) * [5 years, 3 months ago](https://wordpress.org/support/topic/plugin-increases-server-load-time/) * When I have the plugin enabled I get the following error when testing with Lighthouse: * > Reduce initial server response time * When I disable the plugin, the page speed score goes up.
