We are running a Confluence server on premise, version 5.8.5. Response times, from login to browsing, are very long. Moreover, confluence-server.log contains a lot of occurences of this message:
Required plugin module com.atlassian.plugins.atlassian-nav-links-plugin:rotp-menu was either missing or disabled
Our Confluence is running on Java 1.8.0_45, with an Apache Tomcat 8.0.23, which seems to be compatible if I'm not wrong.
Would anyone have a clue on the possible cause of this problem?
Thanks a lot,
About the error message regarding the NavLinks plugin, you confirm if this plugin is actually disabled or missing through the manage Add-ons page on Confluence, browsing for System Add-ons.
However, I don't believe this is the cause of the performance issue.
There are several possible causes for performance issues, so it's hard to point what might be causing the specific issue you're having without taking a good look on log files. The most usual symptom is out of memory issues, which you can try to find on your atlassian-confluence.log file, searching for "outOfMemory".
Other possibilities and tests you can perform are mentioned in our Performance Tuning guide, so I suggest you take a look on this, and in case you can't find out what is causing the issue, I suggest you raise a support ticket with us through support.atlassian.com so that we can provide you full assistance.
Hi Luiz, Thank you for replying! I checked the system plugins upon your remark, and saw that the NavLinks plugin was not enabled. So, I clicked the "enable" button, but it is failling, and in the Confluence server log I see the following error: 2015-08-27 17:18:49,392 ERROR [http-bio-8443-exec-7] [atlassian.plugin.manager.DefaultPluginManager] enableConfiguredPluginModule There was an error loading the descriptor 'null' of plugin 'com.atlassian.plugins.atlassian-nav-links-plugin'. Disabling. -- referer: https://share.groupeonepoint.com/plugins/servlet/upm/manage/system | url: /rest/plugins/1.0/com.atlassian.plugins.atlassian-nav-links-plugin-key | userName: jiraadmin Talking about memory or other perfomance tuning tips, everything seem all good (plenty of memory available, ...). I am wondering if this is not a JDK version problem, or something like this... Thanks, F.

What kind of database are you running with it? You may want to check if it is the latest you can use with that version of confluence. Either way, it doesn't seem like you are alone in this. I have come across a few other people here saying the same thing about their confluence instance after updating to 5.8.x
Maybe the plugin is corrupted? Could you try to re-install that?
Also we had some issues with JAVA 1.8.0_45 and Cofluence 5.8 over SSL as you can see here:
It was fixed Confluence 5.8.8. I know it isn't the same issue, might be related.
