Internet Protocol bandwidth measuring tool Iperf is a modern alternative for measuring TCP and UDP bandwidth performance, allowing the tuning of various parameters and characteristics.
- Measure bandwidth, packet loss, delay jitter
- Report MSS/MTU size and observed read sizes.
- Support for TCP window size via socket buffers.
- Multi-threaded. Client and server can have multiple simultaneous connections.
- Client can create UDP streams of specified bandwidth.
- Multicast and IPv6 capable.
- Options can be specified with K (kilo-) and M (mega-) suffices.
- Can run for specified time, rather than a set amount of data to transfer.
- Picks the best units for the size of data being reported.
- Server handles multiple connections.
- Print periodic, intermediate bandwidth, jitter, and loss reports at specified intervals.
- Server can be run as a daemon.
- Use representative streams to test out how link layer compression affects your achievable bandwidth.
