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 you find a server IP or hostname on a forum or an old list, do not assume it works. You can verify it yourself using the netperf command-line tool. Use -T flags to pin netserver to specific
Public Netperf servers are rare because they are easily abused for DDoS attacks. Most modern testing has shifted to iPerf3, but for those who need Netperf’s specific latency metrics, these are the primary reliable options: You can verify it yourself using the netperf
