Dashboard takes very long to load


after logging in with sunstone as oneadmin, the first shown page is the dashboard. After upgrading from version 3.8.1 to 5.4.1, sunstone often needs a very long time to load the dashboard, sometimes so long that a message ‘Cannot contact server. Is it running and reachable?’ appears . What are the possible reasons for that, or where can I find logs related to that problem? I already looked in sunstone.log and oned.log, but could not find relevant information.


I had a similar issue, it was related to long running queries that the dashboard was calling to get the vm information, using the new feature to clean up the database and adding some caching has solved the problem for me though.
