To determine the optimal number of worker processes for your specific setup, follow these steps:
1. Determine the Number of CPU Cores:
- Use the `lshw` command to show hardware information and identify the number of CPU cores available on your system[2].
2. Set the Number of Worker Processes:
- Set the `worker_processes` directive in the NGINX configuration file to the number of CPU cores. For example, if your system has 4 CPU cores, set `worker_processes` to 4[1][2].
3. Evaluate Server Performance:
- Monitor your server's performance and adjust the number of worker processes based on the number of CPU cores. This ensures that each worker process runs on a separate CPU core, maximizing performance[1].
4. Consider Additional Factors:
- If your server has multiple CPU cores, you may want to set the number of worker processes to a multiple of the number of CPU cores to handle high volumes of connections efficiently[1].
- If your server has a high volume of connections, you may need to adjust the `worker_connections` setting to handle more simultaneous connections[2].
By following these steps, you can determine the optimal number of worker processes for your specific setup, ensuring efficient handling of requests and optimal server performance.
