LiteSpeed Upgrade

LiteSpeed Server Racks

Sigillum-Rasa recently completed our server upgrades to LiteSpeed technology. 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 available today!

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 took less than 15 minutes with zero downtime. Unlike other frontend proxy-based solutions, LSWS replaces all Apache functions, simplifying use and made the transition from Apache smooth and easy.

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 manages static content faster, taking advantage of high-performance kernel syscalls, while LSAPI maximizes PHP performance. LSWS handles users, traffic spikes, and neutralizes DDoS attacks without adding any new hardware.

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 continuously work 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.

Reduces Support Costs

LiteSpeed’s licensing costs are far less than the hardware upgrade required to pursue (and not necessarily attain) the same results with Apache. Switching to LiteSpeed Web Server was quick and painless with minimal costs during the switch. LSWS will reduce the support costs in the long run by allowing us to keep the hosting control panel and interface many users are already familiar with while and relieving us of the troubles of overloaded servers. CPanel even supports it!


LiteSpeed Load Balancer (LSLB) is a high-performance HTTP load balancer application. LSLB is feature-rich, secure, and efficient, offering more flexibility than similarly-priced load balancing software. LSLB is an excellent choice to scale applications beyond one server — both to improve service speed as well as reliability in case of hardware failure.

LiteSpeed Server Application Programming Interface (LSAPI) explicitly allows for seamless, optimized communication between LiteSpeed Web Server and third-party web applications. Using LSAPI with LSWS, we have seen 50% greater performance than Apache with mod_php. LSWS plus LSAPI means faster, more stable dynamic web pages.

LiteSpeed’s anti-DDoS proxy service allows us to redirect traffic to our LiteSpeed specialized servers for intelligent web traffic filtering when they are under attack. LiteSpeed’s proxy service can defend against many of the frequent HTTP attacks that websites face, allowing us to forgo other high-cost DDoS protection plans.
