- For best results test with a wired (copper/fiber) connection.
- The performance of the computer running this test may have a significant impact on the test results.
- Other activity on your network may impact your test results significantly.
- For better results, bypass your network during and outage window and test directly from the Network Access handoff.
- If this is not an option, we recommend connecting your test computer to your network as close as possible to the Network Access handoff.
- 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.
- iperf3 performance is better than web browser based tests.

WiscNet iperf Speed Tests
Iperf Info
- iperf is a network testing tool testing tool used to help measure network throughput, iperf is developed by ESnet / Lawrence Berkeley National Laboratory. For more information please visit:
- WiscNet hosts both iperf2 and iperf3. iperf3
- Use iperf3 per recommendations below
- Both are on the server iperf.wiscnet.net
- iperf.wiscnet.net is only available to WiscNet members
- WiscNet also hosts a perfsonar server, which is available publicly - https://www.perfsonar.net/

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.

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
