Website speed is critical for user experience , search rankings and conversions . A second delay can cause people to bounce and reduce sales. This is the reason why almost all the hosting providers are now using LiteSpeed Web Server instead of the traditional web servers.
LiteSpeed is built to serve your web pages faster and using less server resources. It supports modern web technologies, is highly compatible with popular applications such as WordPress and has built-in caching.
This guide covers how LiteSpeed works, why it’s faster than Apache, and if it’s right for your site.
What Is LiteSpeed Web Server?
LiteSpeed Web Server is a high performance Apache drop-in replacement. Optimized for less cpu and memory usage and more web visitors.
Another big plus is the ability to work with Apache config files including .htaccess so often a website can move to LiteSpeed with no changes to the existing settings.
Today, millions of sites use LiteSpeed, especially sites that demand fast loading speed and consistent performance.
How Does LiteSpeed Work?
LiteSpeed is event driven and DOES NOT spawn a new process or thread per connection.
This allows server to handle thousands of simultaneous connections with lesser system resources.
Your sites load faster and don’t weigh down under heavy traffic.
Why Is LiteSpeed Faster Than Apache?
LiteSpeed has many features that make it much faster than Apache
Event-Driven Architecture
Apache is process/thread based, requires more memory when website traffic increases.
LiteSpeed’s event driven architecture can handle many requests efficiently, reducing server load and improving response time.
Built-In LiteSpeed Cache
LiteSpeed’s greatest strength is LiteSpeed Cache (LSCache).
It caches pages that it has already fetched from the internet. This allows a page to be served immediately on request, instead of generating the page at every request.
The LiteSpeed Cache plugin adds also:
For WordPress sites:
- Cache page
- Cache (for browser caching)
- Images optimization
- Minify CSS & JS
- Load On Demand (Lazy Loading)
- Database Modifications
You don’t need multiple optimization plugins to speed up your site.
HTTP/3 and QUIC Support
LiteSpeed supports the newest web protocols, QUIC, and HTTP/3.
They are intended to minimize delay and loading times , particularly on mobile networks or slow internet connections .
