Improving First-Time Query Performance in SQL Server for Data Migration Scenarios

48 views Asked by At

How can I improve the performance of my initial query execution in SQL Server, given that I do not want to rely on caching because I will not be running the same query again due to data migration between tables?

I have noticed that the first query takes significantly longer compared to subsequent executions which return results much faster.

Is there any way to stop SQL Server from caching for a few executions?

So you are saying that you don't want to use caching, Did you search about disabling the cache on the queries?
