I haven't tried previous builds of Lithium; but I am sure it will happen on them as well.</p> <p>The steps are:</p> <ul class="alternate" type="square"> <li>Download and unzip distribution-karaf-0.3.0-Lithium.zip</li> <li>Start the controller (bin/karaf)</li> <li>Wait about 5 minute for controller start to finish</li> <li>Install netconf (feature:install odl-netconf-connector-ssh)</li> <li>Took over 10 minutes for install to finish.</li> </ul> <p>I have attached the karaf.log. See the timestamps in the following snippet from it:</p> <p>2015-06-23 09:12:27,661 | INFO | pool-8-thread-1 | DeferredResourceConfig | 219 - com.sun.jersey.jersey-server - 1.17.0 | Instantiated the Application class org.opendaylight.aaa.idm.IdmLightApplication<br/> 2015-06-23 09:22:18,449 | INFO | config-pusher | HydrogenDataBrokerAdapter | 194 - org.opendaylight.controller.sal-binding-broker-impl - 1.2.0.Lithium | ForwardedBackwardsCompatibleBroker started.</p> <p>Operating System: All<br/> Platform: All</p> NETCONF-32

Feature install of odl-netconf-connector-ssh is very slow

We have found a workaround, by disabling the Bouncycastle security provider (the default JDK one does not cause this issue) : </p> <p><a href="https://wiki.opendaylight.org/view/OpenDaylight_Controller:Netconf:Testtool#Slow_creation_of_devices_on_virtual_machines" class="external-link" target="_blank" rel="nofollow noopener">https://wiki.opendaylight.org/view/OpenDaylight_Controller:Netconf:Testtool#Slow_creation_of_devices_on_virtual_machines</a></p> <p>Could you try disabling BC provider according to the link above and also removing lib/ext/bcprov-jdk15on-1.52.jar in your distribution ? Then just try again.</p> <p>Can you provide the more detailed information for your environment ?
