NTttcp
NTttcp is Microsoft’s network throughput benchmark, the Windows-native counterpart to iperf3. Like iperf3 it requires a sender and a receiver, one on each end of the link. Microsoft also maintains ntttcp-for-linux, so a mixed Windows and Linux path can be benchmarked with the same tool family on both ends.
Availability
| Platform | How to get it |
|---|---|
| Windows (native) | download from the NTttcp GitHub releases |
| Windows (Cygwin) | not packaged; run the native Windows binary |
| Fedora / Ubuntu | build ntttcp-for-linux from source |
Examples
- Receiver side (
-r), using 8 threads, listening on its own address:
ntttcp -r -m 8,*,<receiver IP>
- Sender side (
-s), matching parameters, run for 60 seconds:
ntttcp -s -m 8,*,<receiver IP> -t 60

- ctsTraffic, another Microsoft traffic generator. It is better suited to long-running reliability and connection churn testing than to raw throughput numbers.
