| Iperf was orginally developed by NLANR/DAST as a tool for measuring |
| maximum TCP and UDP bandwidth performance. Iperf allows the tuning |
| of various parameters and UDP characteristics. Iperf reports |
| bandwidth, delay jitter, datagram loss. |
| |
| iperf3 is a new implementation from scratch, with the goal of a |
| smaller, simpler code base, and a library version of the |
| functionality that can be used in other programs. iperf3 has also a |
| number of features found in other tools such as nuttcp and netperf, |
| but were missing from iperf2.x. |
| |
| Some new features in iperf3 include: |
| |
| * reports the number of TCP packets that were retransmitted |
| * reports the average CPU utilization of the client and server (-V flag) |
| * support for zero copy TCP (-Z flag) |
| * JSON output format (-J flag) |
| |
| Note that iperf3.x is not backwards compatible with iperf2.x |
