TCP Optimizer for Linux

A Python-based utility designed to easily analyze and optimize TCP/IP settings on Linux systems for enhanced internet speed and network performance.

✨ Features

• Interactive TUI: A user-friendly Terminal User Interface to guide you through optimization.
• Automatic Analysis: Analyzes your current network speed to recommend and apply the best TCP profile.
• Pre-defined Profiles: Choose from a list of profiles optimized for different scenarios (e.g., high throughput, low latency).
• Benchmarking: Automatically runs a speed test before and after applying changes to measure the impact.
• Safe Revert: Backs up your original settings and allows you to restore them with a single command.
• CLI Support: Includes a command-line interface for automation and scripting.

🚀 How It Works

This tool tunes your system's network performance by adjusting kernel parameters (sysctl) based on proven configurations. Key parameters modified include:

• Congestion Control: Implements modern algorithms like BBR or Cubic.
• Packet Queuing: Sets efficient queueing disciplines like FQ_CoDel.
• Buffer Sizes: Optimizes TCP receive/send memory buffers.
• And much more... (e.g., tcp_fastopen, tcp_low_latency, tcp_mtu_probing).

🛠️ Quick Start

1. Clone the repository:

   https://github.com/rukaachan/tcp-optimizer
   cd tcp-optimizer

2. Install dependencies:

   pip install "speedtest-cli" "typer[all]" "pydantic"

3. Run the interactive optimizer:

   python -m src.main

Advanced Optimization

For maximum performance, this tool can be used alongside other external methods:

• NIC Tuning (ethtool): Adjust network card parameters like ring buffers and hardware offloading.
• QoS (tc): Implement traffic shaping rules to prioritize critical packets.
• System Profiles (tuned): Use system-wide daemons like tuned with profiles such as network-throughput.
• Kernel Updates: Regularly updating your kernel can introduce significant networking improvements.
