7. Anti-Patterns
•
•
•
•
Look for the Magic button
Use SQL Server Profiler
Optimize configuration settings
Collect as much performance data as you can

8. Optimizing SQL Server for SharePoint
• Dedicated SQL Server Instance
• Content Database size
(http://technet.microsoft.com/en-us/library/cc298801.aspx)
• Shrinking Database
(http://www.sqlskills.com/blogs/paul/why-you-should-not-shrink-yourdata-files/)
• TempDB
• I/O
• Memory
• MAXDOP
(http://technet.microsoft.com/en-us/library/cc298801.aspx)
• Statistics
• http://www.microsoftvirtualacademy.com/training-courses/tuning-sqlserver-2012-for-sharepoint-2013-jump-start#fbid=97fCQYgsi9z

9. The Mind Reader
• 2013: finish before release
• The magic number 5
• No memory problems for the WFE

10. SQL DMV Queries
• Queries running in a specified
period of time
• Finding Wait Causes
• Finding Slowest Queries
• Longest Running Queries
• Longest Blocked Queries
• Reads and Writes per
Database
• Queries that use the most I/O
• Queries executed most often
• State of Statistics
• Find Current SQL Statements
• DMV Snapshots
• Effect Queries on Performance
Counters
• Relation between
Performance Counters and
Wait States
• SQL Queries, Performance
Counters, and Wait States
• Queries that use the most CPU
• Finding Missing Indexes
• Queries with missing statistics
• Find databases with most
missing indexes
• Queries running slower than
normal
