3. What impacts performance Infrastructure (Hosting Environment) Configuration (DNN Settings) Modules/Skin Objects Skin Design Traffic Getting the best performance Tuning for the hosting environment Default configuration changes Next Steps/More Drastic Measures Questions?

4. Why? Types of hosting Shared Cloud (Distributed) Virtual Server (VPS) Dedicated Server Location of SQL Server

5. Shared Low cost Low available RAM/CPU Moderate Disk IO Cloud (Old Style – Mosso, etc) Moderate cost Unstable RAM allotment/Moderate CPU Very fast Disk IO VPS Moderate cost Limited RAM (1-2 Gb)/Moderate CPU Moderate-Fast Disk IO Dedicated High Cost High amount of RAM/CPU Moderate-Fast Disk IO

6. SQL Server Location Adds layer of complication to the assessment of other hosting aspects Is locally installed SQL bad? Best configuration? Most secure configuration? Ways to combat issues?

7. Baseline DNN Configuration Host Settings Performance settings Timer mode Schedule configuration Future Concerns Event Log Site Log

8. Recurring errors Improper development practices Slow rendering/Lack of Cache SolPart menu Invalid HTML Number of installed modules

9. CSS Vs. Tables Size Rendering speed Content placement Image/CSS size Skin Objects used Panes used

10. Low Traffic ASP.NET Worker Process Shutdowns Re-configure IIS Use service such as MyWebKeepAlive.com Cloud or other hosting not allocating enough resources High Traffic Database contention Lack of Caching/Compression

11. Start with core settings changes Baseline performance testing DotNetNuke 4.9.0 website SolPart Menu Default Configuration/Shared Hosting Average page load time 3.2 seconds

12. Performance Settings Module Caching Method Cloud/VPS – Disk Shared/Dedicated – Memory Performance Setting Heavy Caching Compression GZip (Unless using 3 rd party) Recommendation changes in 6.2

13. Other Settings Disable Users Online (Yes) Scheduler Mode (Timer) Enable Event Log Buffer (Yes) Auto-Sync File System (No) Scheduler Search Indexer Frequency should be lengthened

14. Almost instant change Unauthenticated requests Reduced load time to low 2 second mark, a 33% improvement Improvement can be greater depending on size of content

15. Evaluation of installed modules, remove un- necessary ones Consider skin change from SolPart to other menu provider. Have seen performance improvements of 30-50% when using CSS NavMenu Consider third-party caching system Have seen consistent improvements with Snapsis Page Blaster
