OptimiZED

A production-ready Bash script for optimizing Linux VPS servers for high-connection workloads (VLESS, WebSocket, Reverse Proxy, CDN, Tunnel, etc.).

Features

• Network Optimization: BBR/BBRv2 congestion control
• Sysctl Tuning: Optimized TCP/IP parameters for high-connection workloads
• File Descriptor Limits: Increased system-wide limits
• Swap Management: Intelligent swap creation based on RAM size
• NIC Optimization: Network interface tuning (GRO, GSO, TSO)
• IRQ Balance: Automatic setup for multi-core systems
• Advanced Tuning: THP disable
• Backup & Rollback: Automatic backups with rollback capability
• Multiple Profiles: General, High-Connection, Gaming, CDN modes

Requirements

• Ubuntu 20.04+ / 22.04+ / 24.04+ or Debian 11+ / 12+
• Root privileges
• Kernel 4.9+ (for BBR support)

Installation

One-line installer (downloads, makes executable, and runs automatically):

wget -O optimized.sh https://raw.githubusercontent.com/zZedix/optimized/main/optimized.sh && chmod +x optimized.sh && sudo ./optimized.sh

Usage

The script provides an interactive menu with the following options:

1. General VPS Optimization - Balanced optimization for general use
2. High-Connection Proxy Mode - Optimized for proxy servers and high-connection workloads
3. Gaming / Low Latency - Optimized for low latency applications
4. CDN Mode - Optimized for CDN and content delivery
5. Rollback - Restore previous configurations from backups
6. Exit - Exit the script

What It Does

• Creates automatic backups before modifying system files
• Detects system information (RAM, CPU, virtualization type, network interface)
• Applies optimized sysctl parameters
• Increases file descriptor limits
• Manages swap files intelligently
• Optimizes network interfaces
• Enables BBR/BBRv2 congestion control
• Configures IRQ balancing
• Disables Transparent Huge Pages

Backup Location

Backups are stored in: /root/vps-optimizer-backups/

Logs are stored in: /var/log/vps-optimizer.log

Safety Features

• Automatic backups before any modifications
• Idempotent operations (safe to run multiple times)
• Rollback functionality
• Error handling and validation
• OpenVZ detection with appropriate warnings
