Network Optimizer Pro - Complete Gaming & Latency Optimization Toolkit

A comprehensive network optimization suite that reduces latency, optimizes routing, and monitors network performance. Think of it as a DIY ExitLag alternative!

🚀 Features

Core Features

• DNS Optimization - Automatically finds and switches to the fastest DNS servers
• TCP/IP Optimization - Tunes network stack for lower latency
• Bandwidth Monitoring - Real-time monitoring of network usage
• Latency Testing - Continuous ping monitoring with statistics
• Network Statistics - Detailed information about your connection
• Process Monitoring - Identifies bandwidth-hungry applications
• Multi-platform Support - Works on Windows, Linux, and macOS

What It Does (Realistically)

1. Optimizes DNS routing - Connects you to faster DNS servers (5-50ms improvement)
2. Reduces TCP overhead - Disables Nagle's algorithm and optimizes TCP windows
3. Identifies bottlenecks - Shows which apps are consuming bandwidth
4. Monitors connection quality - Tracks packet loss and latency spikes
5. System-level optimizations - Registry and sysctl tweaks for gaming

What It DOESN'T Do

❌ Cannot increase your ISP bandwidth beyond your plan ❌ Cannot reduce physical distance latency (speed of light limit) ❌ Cannot create VPN-style proxy routes (use actual VPN/ExitLag for that) ❌ Cannot perform miracles - your base connection still matters

🛠️ Features Breakdown

1. DNS Optimization

Tests multiple DNS providers and switches to the fastest:

• Cloudflare (1.1.1.1)
• Google (8.8.8.8)
• Quad9 (9.9.9.9)
• OpenDNS (208.67.222.222)
• AdGuard (94.140.14.14)

Expected improvement: 5-50ms faster DNS resolution

2. TCP/IP Optimizations

Windows:

• Enables TCP window scaling
• Disables Nagle's algorithm
• Enables RSS (Receive Side Scaling)
• Sets CTCP congestion provider
• Optimizes auto-tuning level

Linux:

• Enables TCP Fast Open
• Sets BBR congestion control
• Increases network buffers
• Enables SACK and timestamps

Expected improvement: 10-30ms lower latency, reduced jitter

3. Network Monitoring

Real-time Bandwidth Monitor:

• Shows upload/download speeds per second
• Identifies bandwidth spikes
• Tracks network interface statistics

Latency Monitor (C++):

• Continuous ping monitoring
• Min/Max/Average latency tracking
• Packet loss percentage
• High-resolution timing

Process Monitor:

• Lists top bandwidth consumers
• Shows connection counts per application
• Helps identify background downloads

4. Windows Registry Tweaks

The advanced script optimizes:

• Network adapter IRQ priority
• System responsiveness
• Gaming task priorities
• TCP window sizes
• DNS cache settings
• Network throttling

⚠️ Important Notes

Administrator/Root Required

Most optimizations require elevated privileges:

• Windows: Run as Administrator
• Linux: Use sudo
• macOS: Use sudo

Restart Required

After running optimizations, restart your computer for full effect.

Backup

Windows advanced script automatically creates registry backup on Desktop.

Compatibility

• Windows: 10/11 (7/8 may work)
• Linux: Most distributions with systemd
• macOS: 10.14+

Safety

All optimizations are safe and reversible:

• Python script: Changes can be reverted
• Batch scripts: Registry backup created
• No permanent hardware changes

📊 Expected Results

Best Case Scenario

• DNS resolution: 20-50ms faster
• Gaming latency: 10-30ms improvement
• Connection stability: Reduced jitter
• Better routing through optimized TCP

Realistic Expectations

Your results depend on:

1. Base connection quality - Fiber > Cable > DSL
2. ISP routing - Some ISPs have better routes
3. Geographic location - Closer to servers = lower latency
4. Network congestion - Peak hours affect everyone
5. Game server location - Physical distance matters most

What Won't Change

• Your ISP's bandwidth cap
• Physical distance to game servers
• ISP's peering agreements
• Network infrastructure quality

🎯 Use Cases

Gaming

• Reduces input lag in online games
• Stabilizes connection during gameplay
• Identifies background apps affecting performance
• Optimizes for competitive gaming

Streaming

• Reduces buffering through better DNS
• Optimizes upload for streamers
• Monitors bandwidth usage

General Use

• Faster web browsing
• More stable video calls
• Better file download speeds
• Network troubleshooting

🔧 Troubleshooting

"Permission Denied"

Run with administrator/sudo privileges

"Module not found: psutil"

Install requirements: pip install psutil

DNS Changes Don't Apply

• Windows: Use ipconfig /flushdns
• Restart network adapter
• Reboot computer

No Improvement

Some factors are outside software control:

• Physical connection quality
• ISP limitations
• Server-side issues
• Network infrastructure

Undo Changes

Windows Quick Reset:

netsh int ip reset
netsh winsock reset
ipconfig /flushdns

Linux: Edit /etc/resolv.conf to restore original DNS

Registry (if backup exists): Double-click the backup .reg file on Desktop

🎓 How It Works

Unlike ExitLag which provides VPN routing with optimized paths to game servers, this toolkit optimizes your LOCAL network configuration:

1. DNS Optimization: Reduces initial connection time
2. TCP Tuning: Reduces per-packet overhead
3. QoS Settings: Prioritizes gaming traffic locally
4. Monitoring: Identifies and removes bottlenecks

Think of it as tuning your car's engine (local optimizations) vs changing the route you drive (VPN routing). Both help, but work differently!
