Hello,
Read this article – https://xstore.helpscoutdocs.com/article/100-how-to-speed-up-my-website , disable unrequired plugins, optimize images, for example, https://gyazo.com/c93e6badbca6048939b1be41601d9c96 , ask for help from the hosting provider side. GTMetrix changed its testing system, and all the sites that had A, B scores get C, E or F. We’ve checked your site using https://tools.pingdom.com/ https://gyazo.com/140bd388d90ffcfadc54e78c2e8e8ee4 – check this topic https://www.8theme.com/topic/speed-issue-with-theme/
