<p>Iperf3 is a tool which can be used to measure how fast your connection to our servers is.</p>
<p>We run iperf3 instances on all our nodes.</p>
<p>To test, run the following:</p>
<pre><code class="language-plaintext"># Replace anything between the brackets with the data provided in the table below.

iperf3 -p [ port ] -c [ address ] # Upload

iperf3 -R -p [ port ] -c [ address ] # Download</code></pre>
<p>Unfortunately, there can only be one connection to the server at a time with iperf3 (though this shouldn't be a problem in most cases)</p>
