UDP Proxy Complete Guide: SOCKS5 Configuration & 2025 Performance Benchmarks

# Latency Measurements Based on Industry Benchmarks
# Compiled from multiple sources (2024)

Test Methodology:
- LAN tests: 16 microseconds (TCP) vs 12 microseconds (UDP)
- Internet roundtrip: 50-200ms typical range
- Gaming scenarios: 120 packets/second standard

| Connection Type         | Typical Added Latency | Notes                        |
|------------------------|----------------------|------------------------------|
| Direct Connection      | Baseline (0ms)       | Reference point              |
| TCP Proxy              | +100-200ms           | Includes handshake & checks  |
| UDP Proxy (SOCKS5)     | +5-15ms              | Minimal overhead             |
| Gaming VPN             | +15-30ms             | Includes encryption          |
| WebRTC (UDP-based)     | +100ms               | For live streaming           |
