6. Servers Design to function Design to Locality
Heavy read operations require more web servers
Heavy write operations require increased SQL IOPS
Heavy services (i.e. Search) require additional application servers
Design to Locality
Global distribution with heavy write may require localized farms

9. Application Databases
Small to moderate size
Moderate transactional volume
Group on moderate cost/performance disk
Analytics
May be quite large
May require isolation
Reporting increases operational overhead

10. Content Databases Practical limit is 200GB
Max supported limit is 4TB*
Create separate databases for:
Site collections with large lists
Large numbers of subsites
Intensive read/write operations
Data isolation (security)
Consider amount of time it takes to backup/restore
Content
* - Requires specific hardware performance criteria and extensive planning

11. Search Databases Crawl databases can be extremely large
High index sensitivity
Heavy transactional volume
Isolate crawl and temp databases
Distribute across spindles and LUN’s
Highest performance disk
Admin
Properties
Crawl

12. Database Management Manually configure auto-growth settings
Defragment indexes on a regular basis
Limit content DB size per site collection
Assign disks based on size, volume and sensitivity
Isolate transaction logs
Implement regular backup schedule to reduce log file size
Enforce quotas

13. Configuration

14. SharePoint Caching Page Disk Object
First request served from content database, output written to memory
Subsequent requests for same resource read from memory
Disk
File-system objects cached by IIS
Database objects not cached
Object
Commonly requested objects stored in memory
Cross-site queries cached in memory

15. Managing Cache Settings
DEMO
Managing Cache Settings

16. IIS Compression Reduces size of files transmitted across the wire
Caches compressed content on disk
Configurable for various file types
Compression range from 0 - 9
Increases CPU utilization on WFE’s
Size hardware accordingly
Does not effect dynamic content retrieved from database

17. Setting Compression Levels
DEMO
Setting Compression Levels

18. Throttling and Locks
SQL Server escalates row locks to table locks (> 5000)
Query throttling reduces the impact of any single request by limiting the amount of data queried
Throttling is configurable and can be altered for administrators and specific time periods
Bit rate throttling controls download speeds of large objects (video, Flash, Silverlight)
Dependent upon BLOB cache

Customization

26. Branding Start with a minimal master page
Minify and consolidate linked files
Reduce size and number of GET operations
Use image stitching (CSS sprites) on pages with a lot of small images to reduce number of requests
Store resources (style sheets, master pages, layout pages, images) on the PHYSICAL file system (i.e. /_layouts/) not the VIRTUAL file system (Style Library, Publishing Images)
Assets in libraries are stored in database
Easy for users to modify but reduce performance

27. Lists

28. List Items
Just because a list CAN hold millions of items doesn’t mean it SHOULD
All user content in all lists throughout entire site collection is stored in a single table in the content database
Consider query impact across site collection
Folders improve view performance NOT query performance
List view web parts are now XSLT based; however, large list displays may still require custom code

29. List Definitions Rows Columns Storage
More than 5,000 rows in a list is “large”
Default throttle limit
Corresponds to SQL lock escalation triggers
Monitor locks if increasing throttle limit
Columns
More columns = more SQL rows
More SQL rows can slow down performance up to 35%
Storage
Use Remote Blob Storage to eliminate storage of large files within SQL
Not intended to increase query performance

30. Instrumentation

31. Developer Dashboard
Developer Dashboard provides metrics on object execution for individual pages
Displays code-level request data for events
Provides drill-down process isolation
Specifies related database queries
Identifies request allocations and control event offsets
Developers can implement monitoring scopes to display component performance data

32. Dashboard Example Total Page Execution Time Related Queries
Control Events
