LiteSpeed PHP, or LS-PHP, is a fast and efficient PHP implementation that connects to the LiteSpeed web server over the FastCGI protocol. LiteSpeed PHP offers a significant advantage over PHP-FPM, another widely used PHP implementation, because it can handle many concurrent requests without overloading memory or CPU. LiteSpeed PHP also lets administrators tune the number of worker processes in the pool to match the site's load. LiteSpeed PHP is a strong choice for high-traffic websites with demanding performance requirements.

LiteSpeed Worker Processes are the number of LiteSpeed processes created to handle general server tasks such as request routing, SSL encryption/decryption, caching, URL rewriting, serving static content, and more. The number of Worker Processes depends on the LSWS license you use, and you can adjust it in the LSWS configuration.
