After that the user details page is shown. Confusing is the part "client: 0:0:0:0:0:0:0:1". Its an ipv6 address. Does the server try to fetch something via ipv6? </p> <p>I disabled ipv6 in Windows but that didn't changed anything.</p> <p>Have you seen a similar case? What can I do to investigate?</p> <p>Server Info: Detail Version 3.9.52.5 (Version 3.9 Build 52 Patch 5) Build Date 21.11.2011 </p>enTue, 08 Aug 2017 11:00:08 -0400https://answers.axonivy.com/questions/2801/ivy-3-9-user-details-loading-very-slow/2802<p>It looks like an ipv6 issue.</p> <p>You have to configure the corresponding ilc file and set the java property <code>-Djava.net.preferIPv4Stack=true</code>.</p> <p>A default .ilc file is locatedf in <code>&lt;engine&gt;/bin/default.ilc</code>. Copy it and rename it to the same name as the used .exe file. E.g. when you start the engine as a service, the <code>XpertIvyServer2Service.exe</code> is used, so and the ilc file must have the name <code>XpertIvyServer2Service.ilc</code>.</p> <p>In the ilc file adapt the below line. If there is already a option set, add the property to the end of the line.</p> <p>Before</p> <pre><code># # Additional vm arguments. # #ivy.vm.additional.options= </code></pre> <p>After the change, the <code>#</code> was removed and property was added:</p> <pre><code># # Additional vm arguments. # ivy.vm.additional.options=-Djava.net.preferIPv4Stack=true </code></pre> <p>A restart of the engine is required, for the changes to take effect.</p>Flavio SadeghiTue, 08 Aug 2017 11:00:08 -0400https://answers.axonivy.com/questions/2801/ivy-3-9-user-details-loading-very-slow/2802
