Better SQL Server memory defaults in 2019

In 2016 I created the Max Server Memory Matrix as a guide for configuring the maximum amount of memory that should be assigned to SQL Server, using an algorithm developed by Jonathan Kehayias. SQL Server 2019 is still in preview as I write this, but I wanted to point out a new feature that Microsoft has

Better SQL Server CPU defaults in 2019

SQL Server 2019 is still in preview as I write this, but I wanted to point out a new feature that Microsoft has added to SQL Server Setup, on the Windows version. On the Database Engine Configuration screen are two new tabs, called MaxDOP and Memory. These are both new configuration options for SQL Server

Proposed SQL Server defaults: max server memory

A few months ago I suggested that the following settings should be the default for most SQL Server instances: Set cost threshold for parallelism to 50 Disable lightweight pooling if it is enabled Disable priority boost if it is enabled Set optimize for ad hoc workloads to enabled Set max server memory (MB) to a

How does the buffer pool work?

Today we’ll begin taking a look at the buffer pool in SQL Server and how it’s normally used. Before we dive too deeply into the buffer pool, we need to remind ourselves of a few fundamentals of how computers process and store information, as that relates to how the buffer pool operates. A computer is
