netperf is a client-server benchmarking tool for measuring different aspects of network performance.
It can measure bulk data transfer as well as request-response workloads, allowing users to examine both sustained throughput and transaction-oriented performance. Tests are controlled by the netperf client with a netserver process running at the other endpoint.
A wide range of command-line controls makes netperf useful for investigating how protocol choices, message sizes and socket settings affect network behaviour.
This is free and open source software.
Key Features
- Uses a client-server model for network benchmarking.
- Measures unidirectional network throughput.
- Supports request-response tests for transaction-oriented workloads.
- Provides TCP and UDP tests through BSD sockets.
- Supports IPv4 and IPv6 networking.
- Can exercise Unix domain sockets on supported systems.
- Allows message and request/response sizes to be configured.
- Provides controls for socket buffer sizes and other network parameters.
- Can report CPU utilisation alongside network performance.
- Supports tests designed to examine both streaming and latency-sensitive workloads.
- Provides separate
netperfclient andnetserverserver programs.
