If you use Microsoft Dynamics CRM 2011 Outlook clients or have client side Microsoft CRM SDK applications, you should enable Dynamic http application SOAP+xml compression per this command, %systemroot%\System32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression /+"dynamicTypes.[mimeType='application/soap%%u002bxml;charset=utf-8',enabled='True']" /commit:apphost

, which should be run when included in a batch file. This information is included in the Whitepaper, "Optimizing and Maintaining the Performance of a CRM 2011 Server Infrastructure", available at www.microsoft.com/.../details.aspx .

Note that if you wish to run this directly from a command prompt on the server, this part of the command, 'application/soap%%u002bxml; should be changed to only have a single percent symbol, like this, 'application/soap%u002bxml;. In addition, if you are able to setup https encryption on the Microsoft CRM Web site, you will see additional gains in reduced data that needs to be sent that will outweigh any loss from the https overhead.

This solution greatly improved performance of our web services, because our web listener wasn't listed at all.

FYI, CRM Update Rollup 3 also addresses some compression issues:

"Assume that you enable the http compression setting on the Dynamics CRM server. In this situation, the Microsoft Dynamics CRM 2011 Outlook client does not receive responses for SDK calls as compressed. This problem occurs because the Outlook client does not send an "EnableDecrompression" http header with the request."
