LVE, or Lightweight Virtual Environment, creates isolated, small environments for every user on the server, and each one of them receives a specific portion of security lockdown features and dedicated resources. LVE guarantees users that their web hosting neighbors won’t inter-access their data on their server, nor will they steal SSD speed, RAM, or CPU from them.
CPU Cores When processing data, an important piece of hardware that is used in the process is CPU. This piece of hardware has sockets with “cores” that each perform requested tasks. Some tips you should keep in mind if you want optimal CPU usage are: 
Make sure your site is up to date, optimized, and tidy, and remove any data or content that it doesn’t need.

Enable using a CDN from your cPanel menu. This will help you offload delivering and searching of your website data, and it will take the strain off the server.

There is less strain on CPU cores if there is a more cached content.
Memory (RAM) Temporary storing data needed to do tasks is RAM memory. Users accessing various pages of your site and MySQL data queries affect this resource, as well as the activities you take on your site. The data is removed once a task is completed, and the space can be used for another task. For optimal RAM usage, you can follow the following tips: 
Optimize.

The latest versions of Themes, Plugins, and Core will ensure that your CMS is tidy. Plugins that you don’t need should be removed in order to avoid draining memory usage with tasks that you aren’t in need of.

Automatic cron tasks should be disabled from running by themselves. In addition, they should be set to run at set intervals of time from the Cron Jobs tab in cPanel.

You will decrease the active tasks that use up RAP from repeated visits by serving cached content to users, so make sure that you install a caching plugin.
Entry Processes The number of processes that enter your account are the entry processes, for instance, SSH sessions, PHP pages accessed by users, and cron jobs. Depending on the type of request that is being made, they are processed fast by the CPU. IO and IOPS IO stands for Input/output, and it is measured in MB per second. This influences the size of write/read data blocks served on your site. IOPS stands for Input/Output Operations Per Second, and it affects write/read data blocks number served on your website. If you optimize other limits properly, you shouldn’t be facing issues with these two as well.
Number of Inodes Inodes are storage spaces used to hold the data of each folder and file under your hosting space. Cage FS Security The thing that defines the LVE limits for each account and doesn’t allow them to interfere with other accounts is the CageFS feature that is offered by Cloudlinux. However, keep in mind that this doesn’t apply to MySQL. Even though the resources are maintained and separated per cPanel account, something that is elementary for all accounts to use is MySQL.
