LiteSpeed Web Server Overview
LiteSpeed Web Server (LSWS) is the only lightweight, high-performance Apache replacement compatible with all major hosting control panels. Upgrading your web server to LiteSpeed Web Server takes 15 minutes and improves your performance while lowering hardware and support costs:
Increased Performance and Stability
With its streamlined event-driven architecture, LiteSpeed Web Server can serve thousands of clients concurrently with minimal memory consumption and CPU usage. LSWS's highly optimized code serves static content faster, taking advantage of high-performance kernel syscalls, while LSAPI maximizes PHP performance.
Increased Server Security
LiteSpeed Web Server is mod_security compatible and has a host of built-in anti-DDoS features, like bandwidth and connection throttling. LiteSpeed's team of dediated developers works constantly to address the Internet's newest security issues — such as SSL BEAST attacks — and release security updates as soon as new attack methods become known.
Reduced Hardware Costs
LiteSpeed's licensing cost is generally far less than the hardware upgrade required to pursue (and not necessarily attain) the same results with Apache. LSWS serves more users, handles traffic spikes, and neutralizes DDoS attacks without new hardware.
LiteSpeed Web Server is compatible with mod_rewrite, .htaccess, and mod_security. LSWS loads Apache configuration files directly and works as a drop-in replacement for Apache with hosting control panels — replacing Apache in less than 15 minutes with zero downtime. Unlike other frontend proxy-based solutions, LSWS replaces all Apache functions, simplifying use and making the transition from Apache smooth and easy.
