min memory per query Option

Use the min memory per query option to specify the minimum amount of memory (kilobytes) that will be allocated for the execution of a query. For example, if min memory per query is set to 2048 KB, the query is guaranteed to get at least that much total memory. You can set min memory per query to any value from 512 through 2147483647 KB (2 GB). The default is 1024 KB.

Increasing the value of query memory generally improves the performance of queries that use hashing or sorting operations, particularly when there is a lot of memory available and few concurrent queries. min memory per query includes memory allocated for sorting and replaces the sort pages option in earlier versions of Microsoft® SQL Server™.

min memory per query is an advanced option. If you are using the sp_configure system stored procedure to change the setting, you can change min memory per query only when show advanced options is set to 1. The setting takes effect immediately (without a server stop and restart).
