Resource Governor on TempDB in SQL Server 2025

Ed Pollack takes a peak at some upcoming functionality:

TempDB is a system database in SQL Server that manages temporary objects for all databases on a server. Because it is a shared resource, it can easily become a performance bottleneck., as well as an opportunity for a single database or even a single query to wreck SQL Server performance.

Because of this, administrators will often give TempDB plenty of space and put its files on the fastest storage available. Even with these precautions, it is still possible for a TempDB-hungry workload to hog space and resources that result in latency or timeouts for end users.

SQL Server 2025 introduces the ability to use Resource Governor to help manage TempDB resources automatically. This article dives into the new feature, how to configure it, and how it can effectively manage TempDB-heavy workloads.

Ed starts with a primer on TempDB and Resource Governor functionality, then dives right in. It’s good to see some love for Resource Governor.
