SQL 2016 – It Just Runs Faster: In-Memory Optimized Database Worker Pool

SQL Server leverages a worker pool for the In-Memory Optimized Database capabilities.  Prior to SQL Server 2016, increasing the size of the pool required you to enable a startup trace flag.


SQL Server 2016 removed the trace flag and updated the design to dynamically adjust the size of the In-Memory Optimized Database worker pool as needed. 


'It Just Runs Faster' - SQL Server 2016 dynamically adjusts the In-Memory Optimized worker pool to maximize scalability and performance.

    Good to hear about this optimisation. You mention ‘a worker pool for the In-Memory Optimized Database capabilities’. This is the first I’ve heard of such a worker pool. I didn’t even know about the trace flag for versions prior to SQL 2016. Do do have any papers or postings about this worker pool or the trace flag ? As a DBA I’d like more information about this.

    Thanks again.
