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!!!

Managing 2010 Perf Hosted by FPWeb

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

Identify Poorly Performing Code & Content

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

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 response from SQL Server will result in queued App requests

As the app slows down, so does SQL

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 Cache-Control Header

Automatically adds far-future-expires headers to resources and 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 and Cacheable

Favicon is configured for caching, and inserted if it is missing, 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.

SharePoint 2010 provides proactive management
