Stairway to SQL Server Extended Events Level 4: Extended Events Engine - Essential Concepts

In this level, we're going to dig a little deeper into the Extended Events engine, its architecture, and fundamental components. It will give you a deeper understanding of why, in general, an Extended Events session is inherently lower in overhead than an equivalent SQL Trace. We'll also investigate how to design our event sessions to minimize any unnecessary overhead during event data collection, even when we need to create relatively complex event sessions to investigate difficult performance problems.  Read more...

Testing the Performance of Individual SQL Statements within a Batch using SQL Prompt

This article is all about using a SQL Prompt snippet to create and run a test harness on a batch of SQL code, to provide performance data. Behind the scenes, the snippet creates and starts an Extended Events event session, inserts and runs the text of the batch of SQL you’ve selected in SSMS, and uses XQuery on the XML event data, to return it in digestible, tabular form.  Read more...
