LiteSpeed Web Server Overview

LiteSpeed Web Server (LSWS) is a high-performance Apache drop-in replacement. LSWS is the 4th most popular web server on the internet and the #1 commercial web server. Upgrading your web server to LiteSpeed Web Server will improve your performance and lower operating costs:

LSWS Is Apache Compatible

LiteSpeed Web Server is compatible with commonly used Apache features, including mod_rewrite, .htaccess, and mod_security. LSWS can load 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.

LSWS Increases 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. LSWS serves more users, handles traffic spikes, and neutralizes DDoS attacks without new hardware.

LSWS Increases Server Security

LiteSpeed Web Server is mod_security compatible and has a host of built-in anti-DDoS features, like bandwidth and connection throttling. We work 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. LiteSpeed Web Server is also supported on Atomicorp's Realtime ModSecurity Rules and Atomic Secured Linux.

LSWS Reduces Hardware and Support 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. Switching to LiteSpeed Web Server is quick and painless, meaning minimal support costs during the switch. LSWS then reduces support costs in the long run by allowing you to keep the hosting control panel and interface you and your technicians are used to while relieving you of the troubles of an overloaded server.

LSWS Increases Profit

Increased efficiency and performance, lowered hardware and support costs — all of this means increased profit for you, whether you're a hosting provider looking to increase density or a site administrator needing to serve traffic quickly. The question is not whether you can afford to switch to LiteSpeed. The question is: How much money are you losing by not switching?
