Iperf
- Iperf is a commonly used network testing tool to help measure network throughput.
...
Iperf is an open source tool
...
- . There are clients for Windows, Mac, Linux, Bsd, etc
...
- .
- Iperf operates where one end is the client, the other is the server. WiscNet runs an
...
- Iperf version 2 server in Eau Claire, WI
...
- .
- The server is restricted to WiscNet IP addresses.
...
- Iperf2 and iperf3 are incompatible
- iperf.wiscnet.net runs a TCP Iperf server on the default port (5001)
...
...
...
- runs a UDP Iperf server on port 5002
- iperf.ipv6.wiscnet.net runs a v6 TCP Iperf server on port 5003
...
- iperf.ipv6.wiscnet.net runs a v6 UDP Iperf server on port
...
iperf -c iperf.wiscnet.net -p 5002 -b 1g -t30 -i2 -P10

Some common Iperf flags
Enter iperf -h or man iperf depending on your operating system. Here are some common flags:
Flag | Details | Example |
---|---|---|
-c | Client mode | -c |
-t | Time to run the test in seconds | -t 30 |
-P | Number of parallel connections | -P 2 |
-u | UDP (default is TCP) | -u |
-b | Bandwidth per thread | -b 250m |
-i | Interval between bandwidth reports in seconds | -i 1 |
-L | Listen on port | -L 6001 |
-r | bidirectional test | -r |
Examples
Unidirectional 1Gbps circuit test

Add -r to do a sequential bidirectional test where it tests upload first, download second. This requires your client to be on a public IP so the iperf server can directly communicate!

TCP vs UDP testing
Iperf uses TCP by default. TCP has built in congestion avoidance. If TCP detects any packet loss, it assumes that the link capacity has been reached, and it slows down. This works very well, unless there is packet loss caused by something other than congestion. If there is packet loss due to errors, TCP will back off even if there is plenty of capacity. iperf allows TCP to send as fast as it can, which generally works to fill a clean, low latency link with packets. If a path is not clean/error free or has high latency, TCP will have a difficult time filling it. For testing higher capacity links and for links with higher latency, you will want to adjust the window size (-w option). See the KB article on TCP performance for more background.
By using the -u option, you have told iperf to use UDP packets, rather than TCP. UDP has no built in congestion avoidance, and iperf doesn't implement it either. When doing a UDP test, iperf requires that the bandwidth of the test be specified. If it isn't, it defaults to 1Mb/s. You can use the -b option to specify bandwidth to test. iperf will then send packets at the request rate for the requested period of time. The other end measures how many packets are received vs how many were sent and reports its results.
Bidirectional tests
When you use the -d or -r options for bidirectional testing, you may need to pick a port other than the default [5001] as the server is listening on port 5001. In the below examples, I random ports above 1024 were chosen.
We found that using the same port (with the -L) option in rapid succession doesn't seem to work.

Installation Guides
Microsoft Windows
- Download and extract iperf2: iperf-2.0.
...
- 9-win32.zip
- Extract the contents of the .zip to any folder
- Open a command prompt and navigate to the extracted iperf2 folder:
- Now you can run your desired iperf test:
Apple macOS
*nix
- Many Lunix and Unix distros will have iperf in official repositories. Make sure to install iperf2 (iperf), not iperf3
Ubuntu
