If you exceed the CPU and / or RAM resources, the website is still accessible, but the usage time will be longer because the CPU and RAM are related to your account's read / write speed. In addition, this causes an upload and download of more web hosting files. If you exceed the features of your package, review the following possible conditions:
1 - You need to review your application and update it to a newer version.
2 - Review all plug-ins, modules or themes you are using and update them to the latest versions.
3 - You need to contact the web developer and review the technical optimization techniques to reduce the use of your website's resources.
This should resolve the problem with your site's high resource consumption on the server. However, no further optimization possible means that you can use a plan that is not compatible with the scale of your project's needs. In such cases, we recommend our PRO hosting plans
