What do "Physical Memory Usage" and "Virtual memory usage" mean and how to prevent it from going up? I also want to know what is the difference between virtual memory usage and physical memory usage in cPanel?

Physical memory is the actual ram on the server the 8GB-16GB-32GB or whatever it may be, virtual memory is memory stored on the hard drive its usually used when ram is maxed mostly on virtual servers.

A note too, unless this is a VPS it looks like the server may be running cloudlinux and you are limited to 1024 MB of physical RAM. Most WHM/cPanel servers are going to have more than 1GB of RAM

Physical memory usage and virtual memory usage are terms that refer to the amount of memory (RAM) being used by a system.
  1. Physical Memory Usage: Physical memory, also known as RAM (Random Access Memory), is the memory that is installed on a computer's motherboard. The physical memory usage refers to the amount of RAM being used by a system at any given time.
  2. Virtual Memory Usage: Virtual memory is a type of memory that is created by the operating system to provide the system with additional memory when the physical memory (RAM) is running low. Virtual memory usage refers to the amount of virtual memory being used by a system at any given time.
In cPanel, the physical memory usage and virtual memory usage statistics show the current memory usage of the server running the cPanel account. If either of these values are consistently high, it may indicate that the server is running low on memory and is having to rely on virtual memory to function. This can result in slow performance and, in some cases, the server may crash or become unavailable.

To prevent high memory usage, you can:
  1. Upgrade the physical memory (RAM) on the server
  2. Optimize the performance of the website or applications running on the server
  3. Reduce the number of processes running on the server
  4. Disable unneeded services and features
  5. Monitor resource usage and make adjustments as necessary
It's important to monitor the memory usage on your server and take action when necessary to ensure that your website or applications are running smoothly and efficiently.
