Iperf provides a tool to measure IP bandwidth using UDP or TCP.
It allows for tuning various parameters, and reports bandwidth, delay jitter, and packet loss. It supports IPv6 and multicast.
perf is a tool to measure maximum TCP bandwidth, allowing the tuning of various parameters and UDP characteristics. Iperf reports bandwidth, delay jitter, datagram loss.
Here are some key features of "Iperf":
- Running Iperf in bidirectional mode
- Removed STDLIB requirement for Iperf
- Client reporting of server side statistics in UDP tests
- Supports IPv6
- Version 2.0.4 allows the selection of the TCP congestion control algorithm under Linux, adds a manpage, and fixes some bugs.
