Query Store and NAV Performance

mcoscasmcoscas Member Posts: 34
Hi everybody,

Does someone know if the activity of the Query store can cause performance problems in NAV 2017 ? Our customer is suffering from performance problems for a few weeks and we suspect that the query store is the origin of the problem...

Thanks in advance for your reply.

    As in most general questions about SQL Server performance problems the answer is 'it depends'.

    In this articular case it depends on type of activity - if customer's SQL Server is bombarded with thousands relatively simple queries per second then the Query Store might potentially have some noticeable impact.

    But in a real life NAV data access patterns the Query Store performance penalty is highly unlikely to be noticeable.
