SQL Server 2016 Query Store performance can be improved through a software that has a single summary table which displays all Query Store properties. The software enables the user to execute predefined actions to modify Query Store properties and edit all modifiable Query Store properties in a single overview panel.

The software is designed to help you troubleshoot issues and execute tasks that follow best practices to keep Query Store tuned to the database workload. By optimizing its properties and contents, you can improve the performance of the Query Store, which affects how it captures a history of queries, plans, and run-time statistics for each database.
With the software, you can quickly see all Query Store properties in a single summary table, which is especially helpful if you have multiple SQL Server instances. You can register one or more instances and, for a selected connected instance, display all database Query Store properties in this table. This makes it easy to compare properties across Query Stores, identify the origin of performance problems, and select a Query Store to optimize its performance.
You can also execute predefined actions for a selected database, including clearing Query Store contents, restarting Query Store, recovering from memory or disk corruption, setting Query Store to default settings, keeping only the most relevant data in Query Store, flushing the in-memory cache to disk, and finding and deleting ad-hoc queries executed only once and older than 24 hours.
Finally, you can edit all eight modifiable Query Store properties in a single overview panel. Together with the summary table, this allows for quick selection of Query Stores and optimizing their performance, which is much more efficient than using SQL Server Management Studio.
Overall, we've found this software to be a valuable tool for optimizing SQL Server Query Store performance. It's user-friendly, efficient, and provides all the necessary features to get the job done. We highly recommend it to anyone looking to improve SQL Server performance.
