WiscNet hosted IPERF
Iperf is a commonly used network testing tool to help measure network throughput. Since it is an open source tool, there are clients for Windows, Mac, Linux, Bsd, etc. It will generally give you more detailed results than a browser based speedtest.
Iperf operates where one end is the client, the other is the server. WiscNet runs an IPERF version 2 server in Eau Claire, WI. TCP is port 5001, UDP is port 5002. The server is restricted to WiscNet IP addresses.
Examples
iperf.wiscnet.net runs a TCP Iperf server on the default port (5001). The most basic TCP test:
iperf -c iperf.wiscnet.net -i2
iperf.wiscnet.net runs a UDP Iperf server on port 5002 (-p). this test uses UDP (-u), sends 1gbps (-b) , reports every 2 seconds (-i), runs for 30 seconds (-t), with 10 parallel threads (-P)
iperf -c iperf.wiscnet.net -p 5002 -b 1g -t30 -i2 -P10
Preparation
Note |
---|
Please note that - For best results please test while connected to wired ethernet
- The accuracy of this speed test diminishes with larger bandwidth circuits
- The hardware performance of the computer running this test has a significant impact on results
- Any other activity on your network and any devices between your computer and the Internet will impact your speed.
|
You will see the best results if you schedule a time to disconnect your local network and plug your test computer directly into the WiscNet router.
If you cannot take down your network, we recommend connecting your test computer to your network as close as you can to the WiscNet device and using graphs.wiscnet.net or local monitoring to estimate how much bandwidth is being used before you start your test.
Web Browser based speed test
- http://speedtest.wiscnet.net/openspeedtest - WiscNet's locally hosted web based speedtest. Server has 10gbps connectivty.
- https://fast.com/ - Alternate speedtest hosted by Netflix but served from WiscNet's network

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:
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 5001 | -r | bidirectional test (individually) | -r | -d | bidirectional test (simultaneously) | -d | -V | Use ipv6 (this is required even when specifying an IPv6 address) | -V |
|
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 |
Unidirectional UDP 1Gbps circuit test
Command
Code Block |
---|
iperf -c iperf.wiscnet.net -t 60 -P 20 -u -b 50m -i1 |
Info |
---|
" -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 |

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!
iperf -c iperf.wiscnet.net -p 5002 -b 1g -t30 -i2 -P10 -r
iperf.ipv6.wiscnet.net runs a v6 TCP Iperf server on port 5003
iperf -V -c iperf.ipv6.wiscnet.net -p 5003 -i2
iperf.ipv6.wiscnet.net runs a v6 UDP Iperf server on port 5004
iperf -V -c iperf.ipv6.wiscnet.net -p 5004 -i2 -u
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.
The simultaneous test results may be difficult to read. It looks like only TCP is working. UDP doesn't appear to be working even after upgrading to iperf-2.0.4 [there were supposed to be some bug fixes]. It appears to be a problem in the official distribution according to recent ubuntu forums.
If you do not pick a port it will fail:

BadgerNet Overview
Info |
---|
The overview portion of this document has been created by BadgerNet / AT&T and edited by WiscNet. Its intent is to explain the requirements needed in order to procure accurate circuit testing results |
Internet speed tests results may be impacted by several variables, including
- Tool used to test
- Location of testing laptop/PC in the network
- Time of day when test is run
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.
