🔌 Protocols

TCP Mode

Direct TCP connection for maximum performance:

Client <──TCP──> Server

WebSocket Mode

Browser client support:

Client <──WebSocket──> Server

TLS Mode

Secure connections:

⚡ Performance

Nettest is optimized for high performance:

• Multithreading: One server can support multiple clients
• Asynchronous processing: Efficient CPU and memory usage
• Smart queue: Automatic load distribution between workers
• Minimal latency: Optimized architecture for accurate measurements

📊 Visualization

Real-Time Speed Graphs

• Live speed change visualization
• Detailed upload and download statistics
• Interactive charts with smooth animations

Metrics

• Download speed - Real-time download performance
• Upload speed - Real-time upload performance
• Ping - Network round-trip time (median)
• Jitter - VoIP quality metric (RFC 3550), requires server v2.0+
• Packet Loss - UDP packet loss rate (RFC 6673), requires server v2.0+

Note: Jitter and Packet Loss tests use UDP port 5004 by default.
Open this port on the server firewall: iptables -A INPUT -p udp --dport 5004 -j ACCEPT
