Thanks for writing in!
You haven't shared the website URL and there are multiple URLs in your account, so it's difficult for me to take a closer look at the website in question over here. Please share the website URL so we can take a closer look at the page load time.
As you have tried few possible solutions to optimize the load time, I would also suggest you to take a look at our performance optimization guide as we have also listed few other tools and solutions that can looked at to improve page speed.
Please try out following as well:
- Please make sure that you are using latest version of X Theme, Cornerstone and bundled plugins.
2. Plugins can also cause delay in page load time. I suggest you to test for a plugin conflict. You can do this by deactivating all third-party plugins, and see if the problem remains. If it's fixed, you'll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
