Overview

iperf is an open source tool. There are clients for Mac, Linux, BSD, etc. There is a port for Windows; however, in our testing we found it to lack certain features and to lag in performance.
iperf operates where one end is the client, the other is the server.

WiscNet Server Details

WiscNet runs an iperf version 2 server in Madison, WI. This server has a 10gbps uplink.
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
iperf.wiscnet.net runs a UDP iperf server on port 5001
iperf.ipv6.wiscnet.net runs a v6 TCP iperf server on port 5001
iperf.ipv6.wiscnet.net runs a v6 UDP iperf server on port 5001

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).
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.

Some Common iperf Flags

Enter iperf -h or man iperf depending on your operating system. Here are some common flags:

...

-b 250m

...

-L

...

-r

...

-d

...

Note

The hardware performance of the client running this test has a significant impact on results

WiscNet has noticed that the iperf clients for Linux, Unix, and macOS perform better than the ports for Windows

These commands are for iperf 2, not iperf 3

...

Command

Code Block
iperf -c iperf.wiscnet.net -t 60 -P 20 -u -b 50m -i1

...

" -t 10 " = 10 seconds. Since graphs.wiscnet.net pools every 5 minutes, you can modify the -t parameter to run it long enough for the graphs to reflect the speeds.

On some windows platforms, the above command works great for the upload and the command below generates more traffic for the download

Code Block
iperf -c iperf.wiscnet.net -t 60 -P 10 -u -b 100m -i1

iperf3 Test Examples

We recommend using iperf3 TCP tests with four parallel threads when possible for up to 10Gbps tests. UDP tests (not documented here) may cause a service interruption if not used carefully.

Download Test

iperf3 testing download speeds from the member's perspective, 4 threads in parallel, for 900 seconds/15 minutes, using TCP. The [SUM] row results in Mbits/sec or Gbits/sec.

Code Block
iperf3 -c iperf.wiscnet.net -P 4 -t 900

Speed Testing Tools

Most of our members test their internet connection speeds using online browser based tests against servers hosted somewhere on the Internet, for example, http://speedtest.wiscnet.net/ . These tests work fine for low bandwidth internet services but don’t scale well for high speed internet connections. In order to get an accurate speed test a different testing tool like iperf should be used.

Location of testing laptop/PC in the network

Location of the testing PC/Laptop is critical for accurate test results. Note, from the diagram below, that location D is the best place to test your Internet speed from. The reliability of test results go down as we move the test point to C, B and A.

The configuration and capacity of the laptop is equally critical for the accuracy of circuit testing. Please ensure your laptop network cards and configuration are Gig/Capable.

Time of Day

Browser-based speed test results can also vary based on time of day, depending on the bandwidth consumed by the site users at the time the tests are run. For example, if a site has a 100Mbps connection and the users at the site are already consuming 60Mbps download and 25 Mbps upload sustained bandwidth for their business use, the test results will only show 40Mbps download and 75Mbps upload speeds. Therefore, it is recommended that these tests are run before and after business hours if you are using a browser base testing tool.

Mid-day Testing

Some WiscNet members desire to run speed test during business hours to see if they are getting full bandwidth during the day. In others instances, WiscNet will require the test to by-pass any LAN equipment in order to isolate the testing entirely to the circuit. Note that an accurate mid-day test with iperf will be service impacting. In order to run an accurate test during the day, a test window with be scheduled with WiscNet and in some cases with AT&T and WiscNet. The test will entail disconnecting the red cable, as shown in the drawing below, and connecting a laptop to the juniper switch at point D, thus effectively isolating the WAN from the site LAN. Disconnecting the red cable will disrupt service for the site users.
