Netperf Server List Verified

Netperf is a benchmarking tool used to measure network performance, specifically focusing on bulk data transfer and request/response performance. Unlike tools like ping (which measures latency) or iperf (which often comes with a public list of servers), Netperf does not maintain an official, centralized list of public servers.

This creates a challenge for users who want to test their WAN (Internet) speed without setting up a remote server themselves. This guide covers how to find verified servers and alternative methods to ensure your testing is accurate.

VERSION=$(echo "VER" | nc -q 1 $SERVER_IP $PORT) if [[ ! $VERSION == "Netperf" ]]; then echo "FAIL: Invalid netserver response" exit 1 fi netperf server list verified

A port open and a version string returned does not guarantee the server can saturate a 10G link. For production verification, you must run a high-volume TCP_STREAM test.

The 10-Second Burn-In Test:

netperf -H <server_ip> -p 12865 -t TCP_STREAM -l 10 -- -m 32768

Pro Tip: Use -T flags to pin netserver to specific CPU cores (if you control the remote side). Verified servers should expose their CPU capabilities via a separate metadata endpoint (e.g., curl server/status).

If your goal is simply to test internet speed and you do not want to host your own server, Netperf is often the wrong tool due to the lack of a centralized directory. Consider these alternatives that do have built-in verified server lists: Netperf is a benchmarking tool used to measure

When people refer to a verified netperf server list, they mean:

This is commonly used in:

Before running Netperf, ensure the server port is reachable. Use nc (netcat):

nc -zv <server_ip> 12865

Expected output: Connection to <server_ip> port 12865 [tcp/*] succeeded! Pro Tip: Use -T flags to pin netserver
