📋 Test Before and After

Always test your speed before making changes, then again after each optimization to measure improvement. Document your results for future reference.

Common Causes of Slow Speeds

🚧 Network Issues

• Overloaded proxy servers
• Poor internet connection quality
• Network congestion during peak hours
• ISP throttling or restrictions
• WiFi interference and weak signals
• Outdated network hardware

⚙️ Configuration Problems

• Suboptimal server selection
• Heavy encryption causing overhead
• Inefficient routing protocols
• DNS resolution delays
• Incorrect proxy settings
• Multiple VPN layers (double VPN)

Server Selection and Optimization

🌍Choose the Right Server

Geographic Proximity

• Select servers closest to your location
• Test multiple nearby countries
• Consider regional internet infrastructure
• Avoid unnecessarily distant servers
• Use ping/latency as a selection guide

Server Load Analysis

• Check server load indicators
• Avoid overcrowded servers
• Test different servers at various times
• Monitor connection stability
• Switch servers during peak hours

💡 Pro Tip

Save multiple high-performing servers as favorites and rotate between them based on time of day and performance needs.

🔧Protocol and Encryption Optimization

Protocol Selection

For Speed Priority:

• Shadowsocks with AEAD ciphers
• VMess with TCP transport
• Trojan with minimal settings
• SOCKS5 for simple proxying

Balanced Speed/Security:

• V2Ray with WebSocket
• Shadowsocks with chacha20-poly1305
• Trojan with TLS optimization
• Custom encryption profiles

Encryption Settings

• aes-128-gcm: Good balance of speed and security
• chacha20-poly1305: Fast on mobile processors
• aes-256-gcm: Higher security, slower performance
• none: No encryption (only for testing)

DNS Configuration and Optimization

🌐Fast DNS Servers

Cloudflare DNS

• Primary: 1.1.1.1
• Secondary: 1.0.0.1
• Fast global network
• Privacy-focused

Google DNS

• Primary: 8.8.8.8
• Secondary: 8.8.4.4
• Reliable and stable
• Good global coverage

Quad9 DNS

• Primary: 9.9.9.9
• Secondary: 149.112.112.112
• Security-focused
• Malware blocking

DNS Configuration in Shadowrocket

1. Open Shadowrocket → Settings
2. Tap "DNS" settings
3. Replace default DNS with faster servers
4. Enable DNS over HTTPS (DoH) if available
5. Test and save configuration

🔒Advanced DNS Features

DNS over HTTPS (DoH)

• Encrypts DNS queries
• Prevents DNS hijacking
• Bypasses DNS-based blocking
• May slightly increase latency
• Supported by modern servers

Local DNS Caching

• Reduces repeated DNS lookups
• Speeds up website loading
• Enabled by default in most systems
• Can be configured for longer cache times

• Avoid interference from other devices
• Restart router and modem regularly
• Update router firmware
• Consider mesh networks for large areas

Cellular Optimization

• Check signal strength and coverage
• Switch between carriers if possible
• Reset network settings if needed
• Disable background apps using data
• Use WiFi when available
• Consider carrier data plan upgrades

📱iOS Device Settings

Performance Settings

• Close unused apps to free memory
• Disable background app refresh for non-essential apps
• Turn off automatic downloads and updates
• Reduce motion and transparency effects
• Clear Safari cache and website data
• Restart device regularly

Network-Specific Settings

• Disable "WiFi Assist" in Cellular settings
• Turn off "Private WiFi Address" for known networks
• Disable VPN on Demand for other VPN apps
• Clear network settings if experiencing issues
• Ensure date and time are correct
