Linux Network Optimizer v0.7

This repository contains a Bash script designed to enhance network performance on Linux systems

The script intelligently optimizes network settings based on your system's hardware specifications (CPU, RAM)

It dynamically selects and implements the most suitable queuing discipline from fq_codel or cake, and uses the BBR (Bottleneck Bandwidth and Round-trip propagation time) congestion control algorithm for optimal performance

  • If you prefer, you can refer to the Persian Readme

  • Additionally, the Changelog is available at the provided link.

Key Features

  • Dynamically selects and configures queuing disciplines (fq_codel, cake) based on system resources to minimize latency
  • Implements BBR congestion control for optimal throughput and low latency
  • Adjusts TCP buffer sizes (tcp_rmem, tcp_wmem) based on system CPU and RAM
  • Optimizes netdev_max_backlog and memory buffers for handling high volumes of TCP connections
  • Find the optimal MTU size for improved network performance
  • Provides automatic backup and restoration of original network settings

Prerequisites

The script requires root privileges. If you're not logged in as root, use the following command

sudo -i

How to Use

Run the following command to update your system, install required packages, and execute the optimization script

sudo apt-get -o Acquire::ForceIPv4=true update && \
sudo apt-get -o Acquire::ForceIPv4=true install -y sudo curl jq && \
bash <(curl -Ls --ipv4 https://raw.githubusercontent.com/develfishere/Linux_NetworkOptimizer/main/bbr.sh)
