Resolving Performance Bottlenecks in Physical Servers

Introduction

Physical servers are often preferred for applications requiring high performance. However, over time, performance bottlenecks may arise. In this article, we will outline the steps to identify and resolve CPU and RAM consumption issues.

Identifying Performance Bottlenecks

First, here are some commands you can use to identify performance bottlenecks on your server:

• top: Displays CPU and memory usage on the system.
• htop: An enhanced version of top that is more user-friendly.
• dmesg: Displays hardware errors and system-related messages.

Example Usage

Below are examples showing how to use these commands:

top

When this command is executed, you will see the processes with the highest CPU consumption on the system. To use htop, you may need to install it first:

sudo apt install htop

After installation:

htop

Resolving CPU and RAM Consumption Issues

If a specific process is consuming high CPU or RAM, it may need to be restarted or optimized. Below we will explain how to manage these processes.

1. Restarting the Process

After identifying the process consuming excessive resources, you can restart it by:

sudo kill -9 [PID]

Here, [PID] is the process ID of the process you wish to restart. After the process has stopped, restart the necessary service:

sudo systemctl restart [service_name]

2. Optimization

To reduce RAM usage, it is important to optimize database servers like MySQL. You can make the following adjustments in the my.cnf file:

[mysqld]
innodb_buffer_pool_size=1G
max_connections=150
key_buffer_size=256M

Don't forget to restart the MySQL service after saving the configuration file:

sudo systemctl restart mysql

Conclusion

Resolving performance issues in physical servers is critical for enhancing system efficiency. By following the steps outlined above, you can identify and eliminate bottlenecks in your system.
