Besides some tweaking here and there with the async processing, image pre-loading and so forth, there is a new feature to turn on or off the recently added security feature. The current security feature uses the user’s security privileges to determine if a button is displayed and an entity button will only display if they have the Read access right to the specific Entity. Turning off the security feature prevents the Quick View Menu from making a number of web requests which may improve load performance.
IIS automatically compresses many types of content including script, images and css files to help improve network performance by minimizing the amount of data required to be transferred between the client and server. WCF responses which have a mimetype of ‘application/soap+xml;charset=utf-8’ are not compressed by default by IIS.
Dynamics CRM 2011 Outlook client uses WCF to retrieve data from the server and minimizing the network traffic across these clients especially when there are a large number of Dynamics CRM Outlook client users can have a positive impact on network load freeing up resource for other processes.
With WCF compression enabled you may see up to 30% reduction in response size and you can discover this by analyzing network traffic before and after it is enabled. The largest benefit that can be obtained from compression is by enabling SSL for your Dynamics CRM deployment, even for on-premise. Using SSL you may be able to gain an 80% reduction in the response size for your Dynamics CRM Outlook clients. The side effect to all of this is the impact on server resource in particular CPU when it performs the compression and with SSL, the encryption. Therefore it may not provide benefits in every scenario though weighing up the different aspects of your environment including the amount of users, and performance testing these features may show a positive increase in network performance.
Enable compression using a command line
Open the Command Prompt on the CRM Server.
Run the following command:
%SYSTEMROOT%\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression /+”dynamicTypes.[mimeType=’application/soap+xml; charset=utf-8′,enabled=’true’]” /commit:apphost
Reset IIS for the setting to take effect.
Enable compression by manually updating the ApplicationHost.Config
On the CRM Server Navigate to: C:\Windows\System32\Inetsrv\Config\applicationHost.config and open it with notepad.
The latency and bandwidth test the download speed across the wire from the CRM web site to the client browser. A low latency and high bandwidth is ideal. If your values show a high latency and low bandwidth then your CRM experience may be slow depending on the extremity of the range. For some performance reading you can take a look here.
The above documents should give you a solid understanding of performance related improvements you can apply to your Dynamics CRM deployment.
