This is the story of , the silent sentinel of the local network.

Key Features

• Isolate test traffic from unrelated network traffic.
• Use synchronized clocks for accurate one-way latency measurements.
• Disable adaptive offloads or enable them consistently across endpoints when comparing NIC hardware.
• Repeat tests and use percentiles (p95/p99) rather than only averages.
• Test with realistic MTU and DSCP/QoS settings matching production.
• Monitor endpoint CPU/memory and switch/router counters during tests.
