Was one of the four SQL instances you were monitoring with AppInsight for SQL the SQL instance that Orion itself is using? While I have not seen or heard of any similarly reported issues, I'm trying to determine what the correlation is between the Orion web interface performance and the monitoring of AppInsight for SQL. I would recommend adding back one of the two SQL instances to your monitoring with AppInsight for SQL that is not the same SQL instance as the one Orion is using to store its information and see if the performance degradation issue returns. If it does not, then continue to add these instances back individually one at a time, waiting at least an hour or two between until the problem manifests itself. When that occurs, please provide some color around the last SQL server that was added. Is it the same one that Orion is using? Is it a cluster? What version of SQL is it running? Any information you can provide would be helpful.
