 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?

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

 Shared  Low cost  Low available RAM/CPU  Moderate Disk IO  Cloud  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

 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?

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

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

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

 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

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

 Performance Settings  Module Caching Method ▪ Cloud/VPS – Disk ▪ Shared/Dedicated – Memory  Performance Setting ▪ Heavy Caching  Compression ▪ GZip (Unless using 3 rd party)

 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

 Authentication Providers  By default all are enabled  Average default load time 3-6 seconds for login  Disable ALL unused providers at “Host Settings” level  Doing this with default providers (OpenId and LiveId) resulted in login page load of under 1 second  Must be done at the host level, cannot be controlled by template

 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

 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

 DotNetNuke site  2000 users  300 blog posts  3-4 k forum posts  ~ visitors a day  Shared hosting 1.9~2.4 seconds avg load  Dedicated hosting seconds avg load
