Quick Scan Report – TempDB Showing Growth

In the world of SQL Server performance tuning, keeping a close eye on your system’s TempDB is crucial. Today, I want to highlight a specific aspect of SQL Server health: monitoring the growth of the TempDB database. This topic is part of over 150 standard checks we perform at Stedman Solutions during our comprehensive SQL Server assessments.

Why TempDB Matters

TempDB is a system database in SQL Server, playing a vital role in storing temporary objects like temporary tables, table variables, and indexes. It’s also used for sorting large datasets during query processing. Given its significant role, any unusual growth patterns in TempDB can be a red flag, indicating deeper issues in your SQL Server environment.

When the TempDB files expand this is a very slow process, which causing blocking. By sizing your TempDB large enough will take slightly longer for SQL Server to start up, but you will reduce the need for it to expand, thus reducing the delay or blocking.

This is a bigger issues on SQL Servers that are restarted often, such as weekly for OS updates, but it can pose performance issues for all SQL Servers that do not have a large enough TempDB at startup.
