What is LiteSpeed Web Server

LiteSpeed Web Server (LSWS) is a web server developed by LiteSpeed Technologies as a faster alternative to Apache. It can drop-in replace Apache (.htaccess compatible), is a commercial product with a free version (OpenLiteSpeed), supports QUIC/HTTP/3 natively, and runs on Linux.

LiteSpeed vs Apache vs Nginx

Apache: most flexible, .htaccess works, but process-based = high memory under high traffic. Nginx: event-driven, low memory, great for static files, but no .htaccess support. LiteSpeed: faster than Apache in benchmarks, drop-in replacement for easy migration, native QUIC/HTTP3 support.

LiteSpeed Apache

LiteSpeed benchmarks show: static files 6x faster than Apache. WordPress + LiteSpeed Cache up to 40x faster than Apache in some tests. Native HTTP/2 and HTTP/3 QUIC support reduces latency. Event-driven architecture doesn't spawn new processes per request — less memory than Apache.

LiteSpeed Cache Plugin

LiteSpeed Cache (LSCache) is a WordPress caching plugin that works directly with LiteSpeed Server via server-side cache — faster than other plugin-based caches. Features: page cache, object cache, CSS/JS minification, image optimization, CDN integration.

Setup: WordPress LiteSpeed Cache

If hosting uses LiteSpeed, install free LiteSpeed Cache Plugin from WordPress.org. Basic settings: enable Page Cache, Browser Cache, CSS/JS Minify, Lazy Load images. Test with PageSpeed Insights before and after.

Servers: Hosting LiteSpeed Server

Many Thai and international hosting providers have switched to LiteSpeed for better performance and speed positioning. Examples: SiteGround, HostGator (some plans). Hosting using LiteSpeed is compatible with the LiteSpeed Cache plugin for significant WordPress speed improvements.

Setup: LiteSpeed Cache

Dashboard → LiteSpeed Cache → Cache: Enable Cache. Page Optimization: CSS Combine, JS Combine, HTML Minify enabled. Advanced Cache: Object Cache if Redis available. CDN: set CDN URL if using Cloudflare. Crawler: enable to pre-warm cache after publish or update.

LiteSpeed

LiteSpeed Web Server (Enterprise): license per CPU core $0-179/month. 2 Core VPS pricing is reasonable. 1-Core FREE trial. LiteSpeed has no license cost. OpenLiteSpeed is completely free. Most users don't need to buy their own license since hosting providers handle it.

VPS: OpenLiteSpeed VPS

OpenLiteSpeed (OLS) is the free open-source edition of LiteSpeed with no license fee. Performance is close to Enterprise Edition. Easy installation via script on Ubuntu/CentOS. Limitations: not .htaccess compatible like Enterprise, need to configure virtual host manually.

Frequently Asked Questions (FAQ)

Is there a clear difference between hosting that uses LiteSpeed and Apache?
If you do not use the LiteSpeed Cache plugin, the difference may not be obvious. But if you use LiteSpeed Cache on LiteSpeed hosting, the difference is very clear, especially for WordPress sites with many plugins, because server-level cache is much faster than PHP-level cache like W3 Total Cache or WP Super Cache.
Is it easy to migrate between Apache and LiteSpeed?
Very easy as a drop-in replacement, because LiteSpeed reads .htaccess exactly like Apache. Redirects and rewrite rules work right away without changes. You may need to test some custom .htaccess rules that depend on specific Apache modules.
Can LiteSpeed Cache be used together with Cloudflare?
Yes, very well. LiteSpeed Cache has Cloudflare integration in the plugin settings - just set the API token. When you clear cache in WordPress, LiteSpeed Cache also clears the Cloudflare cache, so you do not need to manually purge Cloudflare every time.
If my hosting does not use LiteSpeed, do I still benefit from the plugin?
The LiteSpeed Cache plugin has some features that work without a LiteSpeed server, such as image optimization (WebP), CSS/JS minify, and lazy load. But page cache will run at the PHP level, which is genuinely slower than LiteSpeed's server-level cache.
