LiteSpeed Web Server
Because performance matters!
- Increased Performance and Stability
- Increased Server Security
- Full HTTP/2 support
- Apache Compatible
Increased Performance and Stability
With its streamlined event-driven architecture, LiteSpeed Web Server (LSWS) shows incredible performance in terms of
both scalability and raw speed. Tests show that it is 10 times faster than Apache, taking advantage of high-performance kernel
syscalls, while LSAPI makes LSWS more than 50% faster in PHP content delivery than Apache (even with with mod_php) when
it comes to dynamic content.
LSWS serves more users, handles traffic spikes, and neutralizes DDoS attacks without new hardware.
* Based on benchmarks performed by LiteSpeed Technologies.
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. 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.
Full HTTP/2 support
LiteSpeed is the first web server to support the HTTP/2 standard. HTTP2/ is the Second Major Revision of the HTTP Network
Protocol created by The Working Group and based on Google’s SPDY network protocol, HTTP/2 is the first major improvement to
the HTTP standard in almost 20 years. As of May 2015, HTTP/2 has been published as RFC 7540.
One of the primary goals when creating HTTP/2 was to maintain high compatibility with HTTP/1.1. As such the HTTP semantics have
not been changed ensuring backwards-compatibility. Browsers will also automatically switch from HTTP/1.1 to HTTP/2 if both they
and the server support it. This switch is both instant and invisible to the user.
