I’m working with SCCM and needed to troubleshoot some client items with task sequences.

Enabling Debug and Verbose Logging

To enable debug logging after installation, create the following registry key:
HKLMSOFTWAREMicrosoftCCMLoggingdebuglogging

To enable verbose logging after installation, change the following value to 0.  You will need to right click on the @Global key and change permissions to allow the current user to change the data in the key.
HKLMSoftwareMicrosoftCCMLogging@GlobalLoglevel

I was recently talking with some good friends about tips for performance and what an IIS Administrator could do on the server side.  I also see this question from time to time in the forums @ http://forums.iis.net.    Of course, you should test individual settings in a controlled environment while performing load testing before just implementing on your production farm. 

• 
  
  IIS Compression enabled (both static and dynamic if possible, set it to 9)  If you are running IIS 6, check this article out by Scott Forsyth.


• 
  
  Run FRT for long running pages (Failed Request Tracing)


• 
  
  Sql Connection pooling in code


• 
  
  Look at using PAL with performance counters ( http://blogs.iis.net/ganekar/archive/2009/08/12/pal-performance-analyzer-with-iis.aspx ) 


• 
  
  Look at load testing using visual studio load testing tools


• 
  
  Log parser finding long running pages.  Here is a couple examples


• 
  
  Look at CPU, Memory and disk counters.  Make sure the server has enough resources.


• 
  
  Same machineKey account across all same nodes


• 
  
  Localize content vs. using UNC based content on a single server (My UNC tag with great posts)


• 
  
  Content expiration


• 
  
  ETAG’s the same across all web-farms


• 
  
  Disable Scalable Networking Pack


• 
  
  Use YSlow or Developer tools in Chrome to help measure the client experience improvements.

Additionally, some basic counters in for measuring applications is: I would recommend checking out the Chapter 17 in IIS 7 Resource kit. it was one of the chapters I authored. 🙂

• 
  
  Concurrent Connections, 


• 
  
  Request Per / Sec,


• 
  
  Request Queued. 

I strongly suggest testing one change at a time to see how it helps improve your performance.  Hopefully this post provides a few options to review in your environment.
