What is LiteSpeed Web Server?

Behind every WordPress website is a web server, like a car’s engine. It processes data and serves your website content to visitors.

Most hosting providers use older web servers running Apache or NGINX. These web servers are good, but they can be a little slow if not configured properly.

On the other hand, LiteSpeed claims to be a more powerful web server to load your WordPress websites much faster.
