New KB: SQL query times out or console slow for certain Microsoft Configuration Manager database queries

Hi everyone, I just wanted to take a minute and let you know that we have a new KB article out for an issue where SQL queries may time out, or the admin console may be slow when running certain Configuration Manager database queries. Note that this issue is specific to environments running Microsoft SQL Server 2016 or Microsoft SQL Server 2014.

The reason this can happen is because of SQL Server Cardinality Estimation (CE) changes that were introduced with SQL 2014 and SQL 2016 that can cause performance issues with certain Configuration Manager queries in some environments, depending on variables such as site configuration, environment complexity, and the general state of load and performance of the SQL server.

For all the details as well as a resolution, please see the following:
