What is physical memory usage in cPanel?

Since the causes and effects of resource usage limits depend on the hosting plan you have chosen, it is better to know some of the common hosting plans.

Hosting Plans

Shared Hosting: As the name suggests, you share the server and its resources with multiple other sites in a shared hosting plan. Since you have to share all your resources like CPU and memory usage, all the other sites have to suffer if one website uses up too much bandwidth. So, many shared servers have CloudLinux OS installed to limit the number of resources each user can consume.

VPS: Virtual private server hosting creates a virtual environment that imitates a dedicated server but within the shared hosting environment. Since you get a larger share of the server hardware and its resources, it is less limiting than shared hosting. But you still have limits to the number of resources you can consume.

Dedicated Hosting: In Dedicated hosting, a single server is available solely for your use. Since you have an entire server dedicated to you, the resource usage limits are much higher. Even if you reach the limits, you can always get more bandwidth for an additional price.

The high physical memory usage in the cPanel problem occurs most commonly in the case of shared hosting plans. While it can happen with other plans, it is less likely as the resource limits are larger.
