LiteSpeed is a webserver that can be used instead of Apache on our server which provides high performance, secure, easy to use functionalities. The LiteSpeed can sometimes be more efficient than Apache webserver for very high-traffic websites without adding any more resources to the server. We can implement LiteSpeed Cache also to improve the performance of such websites.
By default, the cPanel/WHM uses Apache webserver, we can install LiteSpeed webserver on a cPanel server easily. They provide a 15-day trial before making the purchase. You can purchase a LiteSpeed license at https://store.litespeedtech.com
