1. For best results test with a wired (copper/fiber) connection.
2. The performance of the computer running this test may have a significant impact on the test results.
3. Other activity on your network may impact your test results significantly.
   
   1. For better results, bypass your network during and outage window and test directly from the Network Access handoff.
   2. If this is not an option, we recommend connecting your test computer to your network as close as possible to the Network Access handoff.
      
4. graphs.wiscnet.net uses 5 minute polling and averages, so short speed tests that will fall within a 5 minute polling cycle won't be reflected as maximums on graphs.wiscnet.net.
5. iperf3 performance is better than web browser based tests.

WiscNet iperf Speed Tests

...

• iperf is a network testing tool used to help measure network throughput, iperf is developed by ESnet / Lawrence Berkeley National Laboratory. For more information please visit:
  • http://software.es.net/iperf/
  • https://github.com/esnet/iperf

• WiscNet hosts both iperf2 and iperf3.
  • Use iperf3 per recommendations below
  • Both are on the server iperf.wiscnet.net
  . Use iperf3 if at all possible.

• iperf.wiscnet.net is only available to WiscNet members
  • WiscNet also hosts a perfsonar server, which is available publicly - https://www.perfsonar.net/

iperf3 Installation

There are many publicly available guides online. Here are some common examples:

...

iperf3 -c iperf.wiscnet.net -P 4 -t 900 -R

iperf3 -c iperf.wiscnet.net -P 4 -t 900 -R

[SUM] 8.00-9.0100 sec 111 MBytes 928929 Mbits/sec 

<repeats until the test is completed>
<output shortened/omitted>

iperf3 Upload 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. "-R" for reverse added to this test.

iperf3 -c iperf.wiscnet.net -P 4 -t 900 -R

Specifying IPv4 or IPV6

• iperf.wiscnet.net listens on v4 and v6. If you wish to test only v4 or only v6, please use the hostnames below (same server)
  • iperf-ipv4.wiscnet.net
  • iperf-ipv6.wiscnet.net
