iperf3: A TCP, UDP, and SCTP network bandwidth measurement tool
Summary
iperf is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, protocols, and buffers. For each test it reports the measured throughput / bitrate, loss, and other parameters.

From <https://github.com/esnet/iperf> 

• Windows: iperf3 binaries for Windows (built with Cygwin) can be found in a variety of locations, including  https://files.budman.pw/ (discussion thread).

<WRAP center round box >
Iperf is a widely used tool for network performance measurement and tuning. It is significant 
as a cross-platform tool that can produce standardized performance measurements for any network. 
Iperf has client and server functionality, and can create data streams to measure the throughput 
between the two ends in one or both directions. Typical Iperf output contains a time-stamped report 
of the amount of data transferred and the throughput measured.

====== NETWORK PERFORMANCE WITH JPERF/IPERF ======

2024-01-27

Free and openly available, Iperf is a command line tool useful for measuring network performance. In my last post, I introduced some basic command line instructions to run Iperf between two endpoints and showed how the tool can be used to generate and measure both TCP and UDP performance. This time, I’ll discuss Iperf’s graphical cousin: Jperf.

====== Ixia QCheck Free Network Check Software ======

===== Qcheck - Free Network Benchmark Utility =====

   http://www.ixchariot.com/products/datasheets/qcheck.html
   
   Qcheck, the network troubleshooting utility from Ixia, quickly checks network response time, throughput,
   and streaming performance. It even runs anywhere-to-anywhere traceroute!
   
===== Performance Endpoint for Linux (32-bit and 64-bit) =====

   endpoint 
   
   QChenck and IxChariot tests use endpoints (unobtrusive software agents) installed at the source
   and destination points of a test. An IxChariot traffic pair is the two endpoints needed for one traffic session

   Web: www.ixiacom.com
   The latest versions of the endpoints are always available for
   free at http://www.ixiacom.com/support/endpoint_library/
