Agenda
• SharePoint Server Specific Performance• You have 7 seconds• Performance Methodology• Top 10 Tips for Website Speed• Quick Reference• Case Study: sharepoint.microsoft.com• Resources
Top SharePoint Server Perf Killers
• Indexing/Crawling• Backup (SQL & Tape)• Profile Import• Users - Inefficient views (Throttling in 2010 helps)• Timer Jobs – i.e. User Sync for large #s of Users• Poor Storage Configuration• STSADM Backup/Restore (Replace with third party or 2010
unattached recovery)• Large List Operations Delete/Update• Network Saturation/Congestion such as Streaming Video• Misconfigured Network• Joel Oleson SharePoint Server Performance Presentation at:

You Have 7 Seconds
• You have seven seconds to make an impact– Engage interest, or leave forever– Slower sites loose customers– google.com
• 100 ms delay = 20% less searches
– shopzilla.com: • 25% reduction in load time• 7%-12% revenue increase
– findsomeone.co.nz• 25% reduction in load time• 13% more clicks per visitor
• Google recently announced that speed will affect search rankings
• Fortune 500 Speeds http://www.aptimize.com/Upload/docs/fortune.pdf#zoom=75
Performance Methodology
Methodology• Goal: 7 seconds or less• Measure• Improve• Measure
What can we change?• Hardware• Platform• Application
Understanding Website Speed
• Waterfall Diagram– Breaks down page load– Shows everything to
load the page
• Create diagram using– WebPageTest– Fiddler
Sample Waterfall Diagram
• Server vs. Client time

TOP 10 TIPS
1: Hardware + Platform
• Buy good hardware– Dedicated SQL Server– Web Cluster– SCSI RAID– Lots of RAM– Multiple CPUs
• SQL Server– Sizing + tuning + indexing– Blob cache
Goal: Server processing < 1 second
Warning: No secrets here
2. Far-Future Expires
Reduce repeat-view load times 50%+ • Browser caches resources• Doesn’t check again until expiry• Reduces HTTP requests 90%• Challenge: Refreshing changes
Code: Add This HTTP Header to each resource
Expires: Wed, 13 Oct 2010 04:02:35 GMT
3. Gzip Compression
Reduce first view load time 30%-40%• Reduces size:
– HTML– JavaScript– StyleSheets
• No effect on images: (JPEG, PNG, GIF)
Check for HTTP request header
Accept-Encoding: gzip, deflate
4. Optimize JavaScript
Reduce load time 7%-10%• Merge JavaScript files into single file• Shrink JavaScript
– Remove comments– Remove whitespace
• Challenges:– Preserving functionality– Maintenance
5. Optimize StyleSheets
Reduce start render up to 75%• Merge StyleSheets into single file• Shrink CSS in StyleSheet• Place StyleSheet at beginning of HTML• Page render starts after all StyleSheets are
loaded• Challenges:
– Maintenance
6. Image Sprites
Reduce load 5%-15%• Merge images into
multi-image sprite• Change HTML to use
sprite• HTTP requests
reduced• Challenges:
– Maintaining the sprite– Changing HTML
7. Image Inlining
• Reduce load times 1%-10%• Base64 encode CSS background images• Embed encoded data into CSS file• Reduces HTTP requests• Challenges
– Maintainability– Browser compatibility
8. Reduce external references
• Reduce ads and syndication– Ads – YouTube videos– Links to external sites
• Each link opens a new connection– Each increases load time ≈ 0.5 seconds
• Solution:– Load at the end of page– Load in an iframe
9. Flash and Silverlight
• Don’t use– Flash on home page– Silverlight on home page
• Both add– Load time– Start render time
LOADING… 15%
10. Security
• Use Kerberos instead of NTLM– Reduces HTTP 401 network traffic – Requires extra configuration in AD
• Only use SSL where you really need it– Consumes CPU cycles– Content not cacheable
TOP 3 RULES
Rule 1: Compress Everything
Deflate/Gzip Shrink Resample
HTML Yes
JavaScript Yes Yes
StyleSheets Yes Yes
XML Yes
JPEG images Yes Yes
PNG images Yes
GIF images Yes
Silverlight
Flash
Load times reduced 30%. On the Web, Smaller is Better.
Rule 2: Merge Files
JavaScript Images
StyleSheets StyleSheet Images
Merge Files - Results
Load times reduced 20%. On the Web, Less is More
Before After
50% reduction
Rule 3: Increase Caching
• Cache static resources on browser to speed up repeat views
Before After
Repeat view load time reduced from 4.5 to 1.9 seconds
Silverlight + Flash
1. Use JavaScript instead
2. Pay attention to size
3. Remove references
4. Compress images
5. Don’t embed videos
