Session Agenda

• Software Boundaries• What is Performance?• Infrastructure Performance• Hardware Performance• SharePoint Performance• Testing Performance

SPSUtah 2014

• Understand the tested (by Microsoft) performance and capacity limits of SharePoint• General recommendations for average hardware and usage• Many come from MSIT

• > 150,000 employees and vendors• Very large amounts of content• Globally accessed

• Meet various goals including:• Backup and restore to meet standard SLAs• Ensure good performance early on with low hardware standards and low knowledge requirements• Allow configuration to scale and maintain decent performance

Software Boundaries

SPSUtah 2014

What is Poor Performance?

• Increased end user response time• Reduced overall system throughput

SPSUtah 2014

Infrastructure Performance

• Active Directory• Exchange• Desktops• Network Topology• WAN Optimization

• SharePoint Farm• Web Front Ends• Application Servers• Database Servers

SPSUtah 2014

SharePoint Farm Performance• 3-4 Web Servers per DC• 8 Web Servers per SQL Server• Bandwidth and Latency<1 ms• 10 Application Pools per web server• 20 web applications per farm• Search: Indexing• iFilters• # of servers• Scheduling and throttling of crawling

• “Boundaries” vs. “Supported”

Test, Measure, and Re-test

SPSUtah 2014

Search Performance

• Crawl Time: How long does the overall time the crawl takes?

• Corpus Size: How big is the corpus size?

• Indexing Speed: How many documents are being indexed per second?

SPSUtah 2014

Search Performance

• Grouping content sources by speed• Tuning crawling• Protocol• Authentication

• Choosing multithreaded iFilters• Proper infrastructure• Dedicated Query Apps vs Distributed Query Apps

SPSUtah 2014

SharePoint Farm Performance• Authentication Performance• # of round trips• Processing speed of provider

• Fastest to Slowest• Anonymous• Claims Authentication• Kerberos• NTLM (Classic Windows Authentication• Basic• Forms and WebSSO• ADFS

In 2013, Claims is the default. Avoid Classic Authentication.

SPSUtah 2014

SharePoint Farm Performance

• Which Machines cause the bottleneck?

• Watch • CPU• Memory• Disk I/O• Network

12

SPSUtah 2014

SharePoint Farm Performance• Requests per Second (RPS): How many requests you can service? RPS is

used for measuring how many pages are delivered. It can measure how many searches are executed.

• Requests per Hour (RPH): Average user requests in an hour.

• Page Time (TTLB): How long it takes to deliver a page back to the client? Used in conjunction with RPS.

• For example, our farm needs to deliver 100 RPS and pages should reach the client within 5 seconds.

SPSUtah 2014

SharePoint Farm Performance• Understand SharePoint workload• Use RAID 10 over other RAID ##• And yes, RAID 10 for SharePoint is better than RAID 5, 50, 60, etc.

• Separate your database files• ** TempDB ** is the most heavily used DB **• Create a TempDB per proc

• Usage database is very busy• Search database is very busy• Log files separate from data files• Place different databases on different volumes• SQL Server files separate from other uses (e.g. OS files)• Separate your files according to I/O workload.• A single volume may be fast enough to handle several databases.

14

SPSUtah 2014

Common Performance Problems

• Large Lists• Lots of Web Parts importing non-cached data from various

places• Cross-List queries and CBQ Web Parts• Too Deep Site Structures• Too many sites in a site collection• Too many site collections in a Content DB• Too many ACLs

SPSUtah 2014

SharePoint Performance

We will discuss the following:

• Large List Control• Performance Throttling• Developer Dashboard• Great for IT Pros and Developers alike

• Caching• IIS 7.0/8.0• Content Query Web Part

SPSUtah 2014

Large List ControlSo what is new?

• Lists and Libraries hold 50,000,000 items• Recommended List View • Size:• Why 2000 or 5000?

• Server Overload

• Solution: • List View Throttling

SPSUtah 2014

List View Throttling

• Limits the number of list items returned per view. • Operations that exceed this limit are prohibited.

• Recommended to configure at the Web Application level.

• Default List View Threshold values:• 5000 for Users• 20000 for Auditors and Administrator

SPSUtah 2014

List View Throttling

• List can be configured individually via API

• Daily Time Window for Large Queries: Turn off Throttling during a daily window• Comes with a Warning

• List View Lookup Threshold: How many complex fields are allowed• Lookup, Person/Group, or workflow status fields• Result in JOINs

SPSUtah 2014

Performance Throttling

• HTTP Request Monitoring and Throttling: Throttle Performance during high server load• SharePoint monitors performance counters and uses

threshhold values• Get 503 request errors• Timer Job fails to start• PUT request still allowed

• Search can trigger performance throttling and cause issues

SPSUtah 2014

Performance Throttling

• Protects the server during peak loads. Monitors:• Available Memory• CPU %• ASP.NET Queue• Wait time in queue

• Checked every 5 seconds• 3 over limit start throttling, logs events• 1 below limit stop throttling

• Configure via PowerShell and Object Model• Add/Remove counters via Object Model

Caching

• Page Output Cache: for generated HTML markup for future requests • Cache frequently used Lists and reduce round trips to the database

• Object Cache: for common objects and query results • Content Query Web Part• List Views

• Disk-Based (BLOB) Cache: for commonly requested files on WFE disks • Automatically cache BLOBs and reduce round trips to the content

databases

SPSUtah 2014

Object Cache Settings• Configure caching via the Site

Settings• Configure caching via web.config

for Web Applications.• Web.config overrides the Site

Settings.

SPSUtah 2014

Output Cache Settings• Configure caching via the Site

Settings• Configure caching via

web.config for Web Applications.• Web.config overrides the

Site Settings.

SPSUtah 2014

Publishing Site Output Cache (Site Output Cache)

• Now configurable per Site/Web• Use the Publishing Images Library (Images)• Use Pages Publishing Library (Pages)

SPSUtah 2014

Caching

Demo

SPSUtah 2014

IIS 7.0/8.0 Performance

• Design pages for fast downloading and rendering• Lazy loading of large JavaScript files• Clustering images• Reduce image requests

• Reduce the number of secured items in pages• Each secured request results in two roundtrips• Validate credentials• Enumeration of groups the user belongs to

• Leverage IIS Compression• Static Compression• Dynamic Compression

SPSUtah 2014

IIS 7.0/8.0 Performance

• Reduce amount of data sent to client and reduce the number of trips a browser makes.• View State Caching and Reduce Payload.• Cache View State to be used in subsequent post-backs• Minify JavaScript• Remove redundant white spaces and new lines

• Reduce File Requests• Merge multiple JavaScript/CSS files in one request• Microsoft didn’t get the memo on this one in SP2013

SPSUtah 2014

IIS 7.0/8.0 Performance

• Increase static compression level to 9 and dynamic to 9APPCMD.EXE set config -section:httpCompression -[name='gzip'].staticCompressionLevel:9 -[name='gzip'].dynamicCompressionLevel:9

• Change dynamic compression CPU utilization threshold range from 100-

100% (This effectively disables it)APPCMD.EXE set config –section:httpCompression /dynamicCompressionDisableCpuUsage:100 APPCMD.EXE set config –section:httpCompression /dynamicCompressionEnableCpuUsage:100

• Enable caching before insertion into page output cacheAPPCMD.EXE set config –section:urlCompression /dynamicCompressionBeforeCache:true

Content Search Web Part

• Powerful web part for searching, aggregating and rolling up information from literally any source.• Best Performance period!• Security Trimming• Cross Site Collection scoping• Very flexible

• Use Display Templates to customize output.

SPSUtah 2014

Content Query Web Part

• Powerful web part for aggregating and rolling up information from various sources.• Designed to leverage the object cache by caching the query

results.• In MOSS 2007, Disabled by default• In SP2010 and SP2013, Enabled by default

• Best performance when content shares the same permissions and doesn’t change often.

SPSUtah 2014

Custom Code

• Common cause for poor performance• Custom inefficient features

SPSUtah 2014

Testing Performance

• SharePoint Load/Performance Testing• Population tools, performance tuning

techniques

SPSUtah 2014

Developer Dashboard

• Allows monitoring page loads and performance• Information:• Times to render page• Page checkout level• DB query info• Web part processing time• Any critical events or alerts

SPSUtah 2014

Developer Dashboard

SPSUtah 2014

Developer Dashboard

• Always ON for all usersON

• Completely OFF for all usersOFF

NOTE: Ondemand is only available in SP2010

$csvc = [Microsoft.SharePoint.Administration.SPWebService]::ContentService; $devdash = $csvc.DeveloperDashboardSettings ;$devdash.DisplayLevel = "On“; $devdash.Update();

Visual Studio Test Suite

• Test throughout your testing lifecycle of planning, testing and tracking your progress

• Use with TFS to automate builds, deployments and testing

SPSUtah 2014

Fiddler

• Great, light weight tool. Provides quick overview of the website performance.

• Free (still …)

• It can also record scripts that you can use in Visual Studio Test Suite.

• neXpert: Fiddler Add-on that checks for classic performance best practices and produces a HTML report on the issues found in a Fiddler capture.

SPSUtah 2014

YSlow

• Analyzes web pages and suggests ways to improve their performance based on a set of rules for high performance web pages.

• Grades web page based rulesets.

• Suggests performance improvements, summarizes page components, statistics for the page, and provides tools for performance analysis.
