Webinar review of “7 Surprising Database Performance Killers” by Kevin Kline. Kline is a Principal Program Manager at SentryOne and the author of popular IT books like SQL in a Nutshell.
In their words “Learn about these performance killers that most DBAs and Devs are unaware… issues ranging from server-side OS settings, file layout, memory settings, and database design to coding issues like data types and cursors.”
Some highlights of the many SQL Server Bottleneck areas discussed in the webinar:
SQL Server Hardware, OS, SQL Settings – 5-10% of problems
- Balanced power default is antiquated
- SQL Server CPU Licensing
- Single vs Multi-threaded workloads
- Defaults at server and database level
- Trace flags
SQL Server Database Design – 10-15% of problems
- SQL Data types inconsistent and oversized
- Primary and foreign key use
- GUIDs as clustered indexes has major downsides
SQL and T_SQL code – 75-80% of problems
- Database Code quality
- Implicit conversions – Ninja Assassin of performance
Another well done webinar by Kevin Kline “7 Surprising Database Performance Killers”. I give it a thumbs up!
My DBA colleagues… Do NOT be a buzzkill! Right?
p.s. If you continue to listen after the webinar, there is an interesting demo of SQL Sentry. SQL Sentry is a scalable solution for SQL Server performance monitoring.
