Upgrade OpenLiteSpeed to LiteSpeed Enterprise on DirectAdmin
Website speed and server stability shape user experience and site growth. LiteSpeed Web Server stands out for fast loading, low server load, and strong performance during high traffic. This article covers what LiteSpeed Web Server is, the core features of LiteSpeed Enterprise, and how to upgrade from OpenLiteSpeed to LiteSpeed Enterprise on DirectAdmin.
What Is LiteSpeed Web Server
LiteSpeed Web Server is designed for fast-loading websites and smooth performance under heavy traffic. It uses an event-driven setup that handles more visitors while keeping server load low. Since it supports Apache configuration files, switching is simple and stress-free, even when teams need flexibility, such as excluding JS files during performance tuning. This makes it a strong fit for WordPress sites and high-traffic hosting environments.
Both OpenLiteSpeed and LiteSpeed Web Server offer powerful built-in features. These include LSCache for faster page delivery, HTTP 3 support, advanced compression with GZIP and Brotli, and unlimited virtual hosting. Together, these features help websites stay fast, stable, and user-friendly.
