3 Agenda Information Technology Solutions

4 Information Technology Solutions

5 Network Information Technology Solutions

6 Architecture Information Technology Solutions Design to function 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 Web Servers Application Servers Database Servers

7 Boundaries Information Technology Solutions Farm Services Databases Service Applications System Application Configuration Servers 10 application pools Web applications 5 zones 20 managed paths Pages 25 web parts 300 Content 50K Web Applications Site Collections Sites Lists Items 500K 250K 5K 30M

8 Capacity Information Technology Solutions Throughput Scalability Latency Concurrency Capacity

10 Information Technology Solutions

11 Intensity Database Information Operations Technology Solutions Workflow Security Trimming Search Publishing Content Query Collaboration Social Client Access Browsing Frequency

12 Database Information Types Technology Solutions Configuration Central Admin Subscription Social Tagging Search Admin Synchronization Profile Managed Metadata Properties Usage Web Analytics Reporting Search Crawl Content

13 Database Information Calculations Technology Solutions Variable Value # Documents 1,000,000 Average Size 150 KB Total Database Sizing Estimate GB # List Items 3,000,000 # Versions 3 Formula: Database size = ((D V) S) + (10 KB (L + (V D))) Database Size Estimates Content DB Size GB Crawl 22.4 GB Property 7.3 GB Profile 48.8 GB Sync 30 GB All other DB s GB Number of User Profiles 50,000

14 Content Information Databases Technology Solutions Practical limit is 100GB Max supported limit is 200GB 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

15 Search Information Databases Technology Solutions 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 Crawl Properties

16 Application Information Databases Technology Solutions 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 Profile BCS App Registry PerformancePoint PowerPivot Word Automation Analytics

17 Database Information Management Technology Solutions Manually configure auto-growth settings Defragment indexes Limit content database size per site collection Implement regular backup schedule to reduce log file size Isolate search databases Enforce quotas

18 Database Information Performance Technology Solutions IOPS Throughput Latency Seek Time Disk Speed Cache Size Queuing Contention Fragmentation Locks Transaction Log Writes

20 Page Information Controls Technology Solutions Navigation Menus Ribbon Delegate Security Trimming Publishing Fields Search Layout Hidden

21 Page Information Data Queries Technology Solutions Page Master Page Layout Page Navigation Controls Permissions Menu Options Web Parts File System Database Data Sources External

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

23 DEMO Information Technology Solutions Managing Cache Settings

24 Uncustomized Page Information Customizations Technology Solutions Content stored on disk, static elements cached, assemblies loaded Content retrieved from database on each request Customized

25 Customization Information Technology Test Solutions Results Average Performance Delta: ~10% Uncustomized Customized

26 IIS Compression Information Technology Solutions Reduces size of files transmitted across the wire Configurable for various file types Increases CPU utilization on WFE s Does not effect dynamic content retrieved from database

27 CSS, Images Information Technology and HTML Solutions Start with a minimal master page Use CSS overrides do not modify core CSS files! Minify and consolidate CSS files 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

28 Javascript Information Technology Solutions Ribbon requires extensive script Load only necessary linked script files for target users Script on Demand framework handles delay loading for common scripts Custom scripts must be delay-loaded manually Minify and consolidate files Each linked file requires a separate request OOTB script files are minified by default

29 DEMO Information Technology Solutions Measuring Page Performance

30 Information Technology Solutions

31 Large Information Lists Technology Solutions 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 Folders improve view performance NOT query performance List view web parts are now XSLT based; however, large list displays may still require custom code

32 List Definitions Information Technology Solutions Rows More than 5,000 rows in a list is large Index the columns Use search Columns More columns = more SQL rows More SQL rows will slow down performance up to 35% Storage Use Remote Blob Storage to mitigate large document libraries

33 Throttling Information and Technology Locks Solutions 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

37 Data Information Access Technology Solutions Server Object Model Client Object Model CAML (LINQ) PortalSiteMapProvider Web Services Search REST

38 The Need Information for Technology Speed Solutions Quality Speed Client OM Web Services REST CAML Search

39 Managing Information Large Technology Data Solutions Sets Leverage search for mass data retrieval Use CAML queries for targeted item selection Joins reduce performance Maintain SQL indexes for optimal query execution Manipulate item data using in-memory objects

40 Data Information Aggregation Technology Solutions SPSiteDataQuery Allows data to be retrieved across multiple list objects. Provides moderate scalability but has performance implications for large datasets. LINQ to SharePoint Does not work with external (BCS) lists. Can result in suboptimal queries test for performance. Search Data is indexed and not real time (only valid as of last indexing operation). Does not provide context of results (no SPListItem, SPList, SPWeb, etc.). PortalSiteMapProvider Cached, non-real-time data.

41 Developer Information Dashboard Technology Solutions Developer Dashboard provides metrics on object execution for individual pages Displays code-level request data for events Includes related database queries Identifies request allocations and control event offsets Used by developers to isolate performance issues

42 Dashboard Information Example Technology Solutions

43 Code Information Instrumentation Technology Solutions Microsoft.SharePoint.Utilities.SPMonitoredScope provides instrumentation for custom code Subscopes are displayed as children of parent scope Does not work with sandbox solutions SPMonitoredScope Custom Code Events Methods Service Calls Queries
