LiteSpeed Web Server (LSWS) VS webfs

LiteSpeed Web Server Documentation - Server General

webfs is a simple HTTP server for mostly static content.

High Performance
LiteSpeed Web Server is known for its high performance and speed, especially under high traffic conditions. It uses event-driven architecture which helps handle thousands of connections with minimal resource usage.
HTTP/3 Support
LSWS offers full HTTP/3 support, which is beneficial for improved load times and performance by utilizing new protocol advantages over older versions like HTTP/1.1 and HTTP/2.
Built-in Caching
LiteSpeed includes built-in server-side caching mechanisms such as LiteSpeed Cache, which significantly boosts loading times and reduces server load.
Security Features
LSWS provides robust security features, including DDoS protection, support for mod_security rules, and features like reCAPTCHA for login pages.
Compatibility with Apache
LiteSpeed is designed to be a drop-in replacement for Apache, and it is compatible with Apache configuration files (.htaccess), making migration smooth and easy.

License Cost
Unlike some alternatives like Apache or Nginx, LiteSpeed Web Server is a paid software, which means there are licensing costs associated with its use.
Administration Complexity
For those unfamiliar with it, configuring and managing LiteSpeed might present a learning curve, especially for people accustomed to using free, widely-used software like Apache.
Limited Open-Source Contributions
As LiteSpeed is not open-source, it has a smaller community of developers and limited third-party contributions compared to open-source alternatives.
Compatibility Issues
While LSWS is highly compatible with Apache, certain extensions or modules may not be fully supported, leading to potential compatibility issues with some applications.
Resource Usage
Although LiteSpeed is optimized for high performance, it may appear to utilize more resources than needed when not configured correctly, especially in smaller or low-traffic environments.
