Server Performance Bottlenecks: CPU and RAM Consumption Solution Guide

Introduction

Server optimization is crucial, especially when dealing with CPU and RAM consumption issues. This article provides a step-by-step technical guide to identify and resolve server performance bottlenecks.

1. Issue Detection

First, analyze the resource consumption on your server using the following commands:

• top: Real-time system monitoring tool that shows CPU and RAM consumption.
• htop: An advanced version of top command with a user-friendly interface providing detailed information.
• dmesg: Displays kernel messages to help identify system errors.

For instance, run the top command to identify processes consuming high CPU:

top

CPU and RAM Consumption Analysis

When high resource consumption is detected, it is important to determine which processes are causing it. Use the htop command to see which user owns the processes and their total resource consumption.

htop

2. Possible Solutions

Some common solutions for high CPU and RAM consumption include:

• LiteSpeed Web Server: Using LiteSpeed instead of Apache can provide performance improvements.
• MySQL Optimization: You can enhance MySQL performance by optimizing the configuration file (my.cnf).

MySQL Configuration Example

To enhance MySQL performance, add the following settings to your my.cnf file:

[mysqld]
innodb_buffer_pool_size = 1G
max_connections = 200
query_cache_size = 64M

3. Service Restart

It is important to restart the relevant services after making configuration changes. You can use the following commands to restart the services:

sudo systemctl restart mysql
sudo systemctl restart httpd

Conclusion

High CPU and RAM consumption can negatively affect server performance. By following the steps outlined above, you can identify issues and implement suitable solutions to enhance your server's performance.
