Page Performance Methodology Methodology • Page Goal: 5 seconds or less • Measure • Improve • Measure What can we change? • Hardware • Platform • Application • Network

Caching, Caching, Caching Client Cache Page Far Future Expires Server Cache Reduce SQL Round Trips Output Cache Publishing Site Collection Page Webparts Never Cache a Search Results not fully anonymous! Disk Based Caching Blob Cache Atom Feeds & RSS = 5 minutes by default

Gzip Compression Reduce first view load time 30%-40% Reduces size: HTML JavaScript StyleSheets No effect on images: (JPEG, PNG, GIF) SharePoint is configured for Collab workload out of the box… Lots of Reads/Writes Check for HTTP request header Accept-Encoding: gzip, deflate

Memory Out of Memory Minimize App Pools Dedicate App pool to customizations and consolidate all else SQL timeouts Warm up Users Complain about 1 minute render times Intermittent performance issues SpDisposeCheck Check for memory leaks, unclosed – Very common!

Webparts What to watch out for… Watch for closed webparts – very comon Force webpart maintenance page or Designer to delete closed webparts Poor performing webparts Dynamic Navigation – list based or cross site with no caching Cross site rollups Content Query Webpart Why doesn’t SharePoint ship with cross site collection rollups and what’s new webparts??? Performance!!! Msdn: Smart Core.js

Managing 2010 Perf Hosted by FPWeb

Identify Poorly Performing Code & Content Look for memory leaks recycle often and/or fix Avoid App pool memory limits or processor limits Look for processor intensive code Render customizations via load tests Identify Software boundaries Large & Wide lists Deep Large site collections with lots of webs Large DBs TechNet: Plan for software boundaries

Health Rules - Definitions Health Rules Runs on a Timer Job Create your own! Repair Auto- magically!

Performance Optimizations Cleaner Pages and XHTML Compliance Core.js size reduced 12% List retrieval optimized Content DB optimized for scale SQL Blocking reduced with list throttling Performance Point incorporated into SharePoint Server 2010 Distributed Indexing - Each crawl database can have many crawlers associated with it

Performance Controls HTTP Throttling - Every five seconds, a job runs that checks server resources Server CPU, Memory, Request in Queue, and Request Wait After 3 failed checks, server is throttled until a successful check. List Controls – List is automatically throttled to max 5000 items

Health Report – Slowest Pages Extensibility for reporting and possibilities are limitless

Performance Dev Dashboard Selected Scope general info SQL queries Info SPMonitoredScopes and WCF Calls their associated cost web part info Off – default, On, and Ondemand – best practice for intranets!

Top Performance Killers 1. Indexing/Crawling 2. Backup (SQL & Tape) 3. Profile Import 4. Users - Inefficient views (Throttling in 2010 helps) 5. Timer Jobs – i.e. User Sync for large #s of Users 6. Poor Storage Configuration 7. STSADM Backup/Restore (Replace with third party or 2010 unattached recovery) 8. Large List Operations Delete/Update 9. Network Saturation/Congestion, i.e. Streaming Video 10. Misconfigured Network

Why is SQL that important? SQL Health = SharePoint Health! Sub-optimal SQL perf will radiate to other components in the farm Slow Slow Slow response from SQL Server will result in App SQL queued App requests As the app slows down, so does SQL

Database Disk I/O Demand Most Demand Medium Demand Low Demand Search Config *Content.. Temp +SSP Model Tlogs Master New Logging in Service 2010 App Usage * Except during backup and Indexing + Except during Profile Import

Scaling SQL - Up Design is Paramount! Consider the following: Overall SQL Throughput (transactions/sec) Disk throughput (IOPS) Network throughput (MB/sec) Disk backup throughput (MB/sec) Network based backup throughput (MB/sec) Length of maintenance windows (hours -> minutes)

Guideline What you can do to optimize your pages… Minimize HTTP Requests Merges JS, CSS files into fewer files. Merges images into sprites Add an Expires or a Automatically adds far-future-expires headers to resources and Cache-Control Header uses auto URL versioning to ensure cached resources are kept up-to-date Gzip Components Components are Gzipped and cached on the server to reduce CPU load Put Stylesheets at the Top Stlyesheets are moved to the top of the page Put Scripts at the Bottom Scripts can be moved to the bottom (or anywhere) on the page Reduce DNS Lookups External resources can be cached and served from the local server Minify JavaScript and CSS JS and CSS are minified Remove Duplicate Scripts Duplicate JS files, stylesheets and images are removed Configure ETags ETags are stripped from the resources Optimize Images Images can be resampled, and GIFs converted to PNGs Optimize CSS Sprites CSS Sprites are created and organized horizontally Make favicon.ico Small Favicon is configured for caching, and inserted if it is missing, and Cacheable removing a 404 condition.

Summary Memory, Disk and Network are frequent performance bottlenecks SQL is extremely important to SharePoint health and Performance Think IOPS when designing disk arrays Separate work loads: temp, log, search, content. SQL scales up and out. Don’t push the limits upward, but keep manageability and costs in mind when scaling out.
