Presenting at the PASS Summit 2010

I am honored to be selected to present at the PASS Summit for the third time. This November in Seattle I will be presenting the following two sessions:

Top 10 Query Optimizer Topics for Better Query Performance

This session will show you how a better understanding on how the Query Optimizer works can help you to improve the performance of your queries. I will show you the top 10 Query Optimizer topics that can give you the more benefit by focusing both on the concepts and practical solutions. The SQL Server Query Optimizer is a cost-based optimizer which job is to analyze the possible execution plans for a query, estimate the cost of these plans and select the one with the lowest cost. So a better knowledge on how the Query Optimizer works can help both database developers and administrators to get better performance from their databases. Several areas of the query processor will be covered, everything from troubleshooting query performance problems and identifying what information the Query Optimizer needs to do a better job to the extreme cases where, because of the its limitations, the Query Optimizer may not give you a good plan and you may need to take a different approach.

Inside the SQL Server 2008 Data Collector

The SQL Server 2008 Data Collector provides some low overhead data collection functionality to store performance and diagnostics historic information of your SQL Server instances. See how you can use this information to troubleshoot problems and to provide trend analysis for the performance of your SQL Server instance. In addition to show the basics and architecture of the new Data Collector, this session focuses on the predefined system data collection sets that are provided by SQL Server 2008 that automatically collect data from the disk usage, instance activity, and queries statistics. You will learn about the Disk Usage collection set, which gathers statistics regarding the growth of the data and transaction log database files; explore the Server Activity collection set which focus on the server activity and resources utilization; and learn about the Query Statistics collection set which collects data regarding the queries running in your instance.

See you in Seattle!
