Everything you need to know about LiteSpeed Web Server, performance optimization and licensing.
LiteSpeed Web Server (LSWS) is a high-performance, drop-in replacement for Apache. It uses an event-driven architecture that handles thousands of concurrent connections with minimal memory footprint. LiteSpeed is fully compatible with Apache configuration files (.htaccess, mod_rewrite rules, mod_security), meaning you can switch from Apache to LiteSpeed without changing your website code. It includes built-in page caching (LSCache), HTTP/3 with QUIC protocol support, and anti-DDoS protection.
LSCache is a server-level full-page cache built directly into LiteSpeed Web Server. Unlike plugin-based caching solutions that run at the application level, LSCache operates at the web server level, making it dramatically faster. It supports intelligent cache management with ESI (Edge Side Includes), tag-based cache purging, and automatic cache invalidation when content changes. LSCache plugins are available for WordPress, Joomla, Magento, PrestaShop, OpenCart and many other CMS platforms.
LiteSpeed offers license tiers based on worker processes and memory limits. Web Host Lite provides 1 worker with basic features, suitable for small sites. Web Host Essential and Professional offer increased workers and memory for growing businesses. Web Host Enterprise provides maximum workers and memory for high-traffic sites. Web Host Elite offers unlimited resources for the most demanding hosting environments. All tiers include LSCache, HTTP/3, and full Apache compatibility.
Yes, LiteSpeed Web Server integrates seamlessly with all major hosting control panels including cPanel/WHM, DirectAdmin, Plesk and CyberPanel. For cPanel and DirectAdmin, LiteSpeed provides official plugins that enable one-click switching between Apache and LiteSpeed. The transition is completely transparent — all existing Apache configurations, .htaccess rules and mod_rewrite directives continue to work without modification.
Independent benchmarks consistently show that LiteSpeed outperforms Apache by up to 6x for static content and up to 5x for dynamic PHP content. Compared to Nginx + PHP-FPM setups, LiteSpeed with LSCache delivers 2–3x faster page loads for CMS-based websites like WordPress. The performance advantage is most dramatic under heavy concurrent traffic, where LiteSpeed's event-driven architecture prevents the process spawning overhead that degrades Apache's performance.
LiteSpeed licenses are issued per server based on the server's primary IP address. After purchasing a license from BurtiNET, your IP is registered instantly and you can install LiteSpeed immediately. The license key is validated during server startup. If you change your server's IP, you can update the license through your BurtiNET panel. LiteSpeed also offers a free OpenLiteSpeed edition with community support for basic use cases.
LiteSpeed Web Server is the fourth most popular web server on the internet and the fastest-growing alternative to Apache and Nginx. Trusted by millions of websites worldwide, LiteSpeed combines Apache compatibility with cutting-edge performance technology. Its event-driven architecture, built-in page caching and native HTTP/3 support make it the preferred choice for hosting providers who demand maximum speed and efficiency from their infrastructure.
Unlike Apache's process-based model that spawns a new thread or process for each connection, LiteSpeed uses an event-driven architecture that handles all connections within a small number of processes. This approach dramatically reduces memory usage and context switching overhead. A single LiteSpeed worker process can efficiently handle tens of thousands of simultaneous connections, making it ideal for high-traffic websites and hosting environments with many concurrent users.
LiteSpeed Cache (LSCache) is arguably the most impactful feature of LiteSpeed Web Server. Operating at the server level rather than the application level, LSCache bypasses PHP entirely for cached pages, serving content directly from memory at near-static-file speeds. The LSCache plugin for WordPress includes advanced features like image optimization (WebP conversion), database optimization, CSS/JS minification, CDN integration and critical CSS generation — all in a single, free plugin that outperforms premium caching plugins.
LiteSpeed was one of the first web servers to support HTTP/3 with the QUIC protocol. QUIC replaces TCP with UDP, eliminating head-of-line blocking and reducing connection establishment time from multiple round trips to zero (0-RTT). This results in significantly faster page loads, especially on mobile networks with high latency. LiteSpeed's HTTP/3 implementation is production-ready and enabled by default, requiring no additional configuration.
LiteSpeed includes robust security features at the server level. Its built-in anti-DDoS capabilities can detect and mitigate volumetric attacks, connection floods and slowloris attacks without external tools. Full ModSecurity compatibility provides Web Application Firewall (WAF) protection with the same rule sets used by Apache. LiteSpeed's request processing architecture inherently limits the impact of attack traffic, as malicious connections consume minimal resources compared to process-based servers.
