Changes to SQL Server 2012 Execution Plans

I’ve been working with execution plans quite a lot in SQL Server 2012. There are a number of changes, most of them associated with new or different functionality.

A Performance Troubleshooting Methodology for SQL Server

When healing a sick SQL Server, you must forget the idea that there could ever be a simple correspondence between symptom and disease: The art of troubleshooting is much more the art of discovering, and assembling, the various pieces of the puzzle so that you have a complete understanding of what is going on inside of a server.  Read more...

How to Performance Tune the Microsoft SQL Server tempdb Database

If your SQL Server’s tempdb database is heavily used by your application(s), consider locating it on an array of its own (such as RAID 1 or RAID 10). This will allow disk I/O to be more evenly distributed, reducing disk I/O contention issues, and speeding up SQL Server’s overall performance.  Read more...

System Monitor (Perfmon) Counters for SQL Server 2005

Capturing performance monitor counters is of great value to understand how SQL Server is behaving at a macro level, that being how overall resources are being used within the engine. Without this data it is difficult to determine where the performance issues are occurring. Capturing the metrics has been traditionally from Performance Monitor either on an ad-hoc basis or setting up a log to capture the values on a predefined basis.  Read more...
