iperf-3.0-2.lbn13.x86_64

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 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)
