Yes, I have checked the images that you shared with us. The thing is our theme is the most optimized version on the Themeforest. All of our demos are very well optimized once you changed the demo content with yours you need to optimize the site speed based on the results after you changed the content and your server sometimes the server response time is not good. So here is a complete article from our theme to know about the cause of the speed and how to fix it: https://xstore.helpscoutdocs.com/article/100-how-to-speed-up-my-website
I hope it helps.
