Case Study: Hosting4Real achieves lower CPU usage with LiteSpeed Web Server and WAF

Why LiteSpeed and WAF is Pure Love

Hosting4Real, a small Dutch web hosting provider, faced significant performance challenges when running the Comodo CWAF ruleset on Apache. The extensive Web Application Firewall rules were causing severe CPU load, often consuming the equivalent of one to two full cores, which was hurting their system's performance and resource efficiency. They sought a solution from LiteSpeed to address this high resource utilization.

By switching to LiteSpeed Web Server, the company implemented a highly optimized WAF. LiteSpeed's proprietary implementation, which only processes rules for dynamic requests and utilizes an internal cache, dramatically reduced CPU usage. The results were a drop in CPU load of 80-100% even while traffic increased by 10.8%, allowing Hosting4Real to run the full security ruleset with a negligible performance impact.
