Location: Security/Modify Apache Memory Usage
The "Modify Apache Memory Usage" feature will calculate your apache memory usage based on your memory usage history and set a new memory limit for Apache processes. Limiting each process' access to memory will increase the stability of your server but may reduce performance slightly. This is a limit for each Apache process, not for all Apache processes combined.
