Verify LiteSpeed License Core/Worker Numbers
Overview
LiteSpeed Web Server is a high-performance web server that can significantly improve your website's performance. This guide explains how to verify your LiteSpeed license and check core/worker numbers.
What are Core and Worker Numbers?
CPU Cores
The number of CPU cores determines the maximum number of worker processes your LiteSpeed server can run. Each core can handle one worker process.
Worker Processes
Worker processes handle incoming requests. The number of workers should match your CPU core count for optimal performance.
