How to optimize and increase server performance in cPanel or WHM server?

The purpose of the below plugins is to optimize and increase server performance by reducing server loads on a Linux based WHM/cPanel Server. This helps in speeding up the websites that are hosted on a cPanel server.

1. LiteSpeed: LiteSpeed Web Server (LSWS) is compatible with commonly used Apache features including mod_rewrite, .htaccess, and mod_security.

LSWS can load Apache configuration files directly.

Fully integrates with popular control panels, like cPanel, Plesk, DirectAdmin and more.

Switching from Apache to LSWS takes less than 15 minutes with zero downtime.

For WordPress application, LiteSpeed provides LSCache plugin that includes built-in PageSpeed optimization, image optimization service, critical CSS generation service, third-party CDN integration and more.

Total Acceleration with CDN: Typical Content Delivery Networks cache only static content (images, CSS, JavaScript, etc.), and those that claim to cache dynamic content do so blindly. Only truly caches WordPress dynamic content, and it does so intelligently. integrates with LSCache to analyze dependencies and allow unprecedented cache accuracy on a global network scale. Using QUIC as the transfer protocol, reduces transmission time to all of your site’s visitors, no matter where they live.

They have both paid versions and opensource. See the List of products that are offered by LiteSpeed.

2. NGINX: NGINX is open-source software for web serving, reverse proxying, caching, load balancing, media streaming, and more. It started out as a web server designed for maximum performance and stability. In addition to its HTTP server capabilities, NGINX can also function as a proxy server for email (IMAP, POP3, and SMTP) and a reverse proxy and load balancer for HTTP, TCP, and UDP servers. NGINX accelerates content and application delivery, improves security, facilitates availability and scalability.

NGINX Plus: NGINX Plus is a software load balancer, web server, and content cache built on top of open source NGINX. NGINX Plus has exclusive enterprise‑grade features beyond what’s available in the open source offering, including session persistence, configuration via API, and active health checks. Use NGINX Plus instead of your hardware load balancer and get the freedom to innovate without being constrained by infrastructure. See the List of products that are offered by NGINX.

Engintron is absolutely free.

3. Varnish: Varnish Cache is a web application accelerator also known as a caching HTTP reverse proxy. You install it in front of any server that speaks HTTP and configures it to cache the contents.
