What are WHM Tweak Settings used for?
WHM is installed with standard factory settings when it is delivered to you. Those settings can be altered through Tweak Settings. Tweak Settings include every category of function, tools, applications and wizards that you can use in WHM.

The major categories in Tweak Settings are:

- Stats and Logs
Each category has a plethora of subtopics you can explore. To find Tweak Settings, login to your WHM and head to Home > Server Configuration > Tweak Settings.
Common Tweaks for Performance
Turn off Mailman
Used for managing mailing lists, but if you don’t utilize mailing lists in cpanel, disabling would reduce CPU usage
Set email delivery times to retry every 120 seconds
The default is 60 seconds, again, to reduce CPU usage
Set Initial default/catch-all for Accounts Behavior to Gail
This is to mitigate CPU usage as well as received SPAM. If emails are sent to inboxes that don’t exist, this option would reject those messages
Turn Off Boxtrapper, Spam Trap and SpamAssassin
Another setting to reduce CPU usage, though if having spam issues in your inbox could be later re-enabled.
Turn Off Analog Stats and Webalizer Stats
Statistic tracking on the server will add to CPU usage. Utilizing an outside service such as Google Analytics will give better tracking information, without the server overhead.
Turn On Conserve Memory
This setting allows you to specify whether to conserve memory (RAM) at the expense of more CPU usage and disk I/O. For low memory systems (2-4GB), this would be recommended to be enabled. This setting defaults to Off.
Number of pigz Processes
This should be set to the number of CPU cores you have on the system, the default is set to 1.
These settings will help you to maximize your CPU usage and overall performance.
