MTU Optimizer

A command-line tool that finds the optimal MTU (Maximum Transmission Unit) size for your network connection by testing different values and analyzing latency, jitter, and packet loss.

Features

• Dynamic Progress Bar: Real-time progress tracking during MTU testing
• Comprehensive Analysis: Latency (min/avg/max), jitter, and packet loss statistics
• Clean Results: Identifies optimal and worst-performing MTU values
• Flexible Output: Text table or JSON format
• Customizable Testing: Configurable MTU range, step size, and ping count

Quick Start

# Build the application
make build

# Run with default settings (tests MTU 1200-1500)
./build/mtu

# Test specific range
./build/mtu --min-mtu 1400 --max-mtu 1460 --step 10

# Verbose output with detailed information
./build/mtu --verbose --requests 3

Installation

# Install dependencies and build
make deps
make build

Usage Examples

Basic Optimization

./build/mtu

Tests MTU range 1200-1500 with step 8, showing progress bar and results table.

Custom Target and Range

./build/mtu --target 1.1.1.1 --min-mtu 1400 --max-mtu 1500 --step 20

Fast Testing

./build/mtu --min-mtu 1450 --max-mtu 1470 --step 5 --requests 2

JSON Output

./build/mtu --format json --min-mtu 1400 --max-mtu 1450 --step 10

Verbose Mode

./build/mtu --verbose --debug
