Ultimate Linux Performance Optimizer

A powerful Bash script for optimizing system performance on Linux, specifically tuned for AMD Ryzen processors and NVIDIA GPUs. This tool provides an interactive menu to easily switch between performance modes and optimize CPU, GPU, and system settings.

🎯 Features

• 🚀 Ultimate Performance Mode: Maximum CPU and GPU performance for gaming and heavy workloads
• ⚖️ Balanced Mode: Optimized daily use with good performance and efficiency
• 🔋 Power Saving Mode: Reduce power consumption when on battery or idle
• 📊 Real-time Monitoring: View detailed CPU, GPU, and memory status
• 💾 Persistent Settings: Option to save configurations across reboots
• 🎨 Color-coded Interface: Easy-to-read terminal output

⚙️ System Requirements

• OS: Any Linux distribution with cpupower (tested on Arch Linux)
• CPU: AMD Ryzen processors (tested on Ryzen 5 1600, works with other CPUs)
• GPU: NVIDIA graphics card (tested on GTX 1660 SUPER)
• Privileges: Root access required

📦 Dependencies

Required

sudo pacman -S cpupower

Optional (for GPU optimization)

sudo pacman -S nvidia-utils nvidia-settings

For other distributions:

• Debian/Ubuntu: sudo apt install linux-cpupower nvidia-utils
• Fedora: sudo dnf install kernel-tools nvidia-settings

🚀 Installation

1. Clone the repository:

git clone https://github.com/levent1ozgur/linux-performance-optimizer.git
cd linux-performance-optimizer

2. Make the script executable:

chmod +x performance-optimizer.sh

3. Run the script:

sudo ./performance-optimizer.sh

📖 Usage

Run the script with sudo privileges:

sudo ./performance-optimizer.sh

Menu Options

1. Ultimate Performance Mode

• Sets CPU governor to performance
• Maximizes CPU frequency and boost
• Sets GPU to maximum performance mode
• Optimizes VM dirty ratios and swappiness
• Ideal for: Gaming, video editing, compiling, benchmarking

2. Balanced Mode

• Sets CPU governor to schedutil or ondemand
• Adaptive performance based on load
• GPU adaptive performance
• Default system settings
• Ideal for: Daily use, multitasking, general computing

3. Power Saving Mode

• Sets CPU governor to powersave
• Limits maximum CPU frequency
• GPU power-saving mode
• Ideal for: Battery life, light workloads, background tasks

4. Show Detailed Status

• Displays CPU information and current governor
• Shows GPU status, temperature, and utilization
• Memory usage statistics
• Current frequencies for all cores

🔧 What It Optimizes

CPU Optimizations

• CPU frequency governor (performance/balanced/powersave)
• Scaling frequency limits
• Energy performance bias
• Per-core frequency management

GPU Optimizations

• PowerMizer mode control
• Texture filtering quality
• OpenGL image settings

System Optimizations

• VM dirty ratio (write caching)
• Swappiness (swap usage aggressiveness)
• File descriptor limits
• Network buffer sizes

⚠️ Important Notes

• Always run with sudo: Root privileges are required to modify system settings
• Settings are temporary: Unless you choose to make them persistent, settings reset on reboot
• Persistent mode: Uses systemd's cpupower.service to apply settings at boot
• GPU optimization: Requires NVIDIA proprietary drivers and nvidia-settings
• Heat warning: Performance mode generates more heat - ensure adequate cooling

🔄 Making Settings Persistent

When choosing a performance mode, the script will ask:

Make these settings persistent across reboots? (y/n):

Selecting y will:

• Enable the cpupower systemd service
• Configure /etc/default/cpupower with your chosen governor
• Apply settings automatically on every boot

📊 Monitoring

To monitor system performance while running the optimizations:

# CPU frequencies
watch -n 1 'grep MHz /proc/cpuinfo'

# GPU monitoring
watch -n 1 nvidia-smi

# Temperature monitoring
sensors

🛠️ Troubleshooting

Script says "cpupower not found"

sudo pacman -S cpupower

GPU optimizations not working

• Ensure NVIDIA proprietary drivers are installed
• Check if nvidia-settings is available
• Verify GPU is properly detected: nvidia-smi

Settings not persisting

• Check if cpupower.service is enabled: systemctl status cpupower
• Verify /etc/default/cpupower exists and has correct permissions

Performance mode causing system instability

• Switch to balanced mode
• Check system temperatures
• Ensure adequate power supply and cooling
