CRM 2011 Performance issue

  • Artikel

Issue:

It’s taking more than 20 to 25 seconds to load the application on CRM outlook client.

Environment:

CRM 2011 ( Single server)

Client: Windows XP 32 bit with outlook 2010

Troubleshooting:

· It took 10 to 15 seconds to load the CRM application on outlook 2010.

· Whenever we try to open a CRM application, the virtual desktop machine CPU usage was constantly at 100% ( Outlook.exe à 50 % to 97 %).

· Provisioned a new virtual desktop with 2 CPU ( 2.86 GHz).

· Did the following optimization and confirmed that the its taking 4 to 5 seconds to load the screen. The CPU usage was normal ( 20% to 40%) :

Ø Disabled the un-wanted add-on’s on outlook.

Ø By passed the proxy for the local intranet sites.

Ø Added the site under Local Intranet on IE.

Ø Reset the client outlook plugin using the following command line:

C:\Program Files\Microsoft Dynamics CRM\Client\ConfigWizard\Microsoft.Crm.Client.Config /reset

· Tested the Latency:

Ø Client to Application server à Less than 1ms

Ø CRM Application Server to SQL server à Less than 1ms

Ø SQL server to CRM Application server à Less than 1ms

· Ensured that CPU/Memory usage is normal on SQL and CRM servers.

Additional Information & Recommendation:

· As per Microsoft recommendation “Microsoft Dynamics CRM for Outlook hardware requirements”, we need to increase the CPU on all the virtual desktops

· Bypass the Proxy Server for On-premise Deployments within a LAN using group policy.

· Add the web site under local intranet zone on IE using group policy.

· On the virtual desktop check the behaviour by disabling .Net setting called Expect100Continue feature on CRM outlook config file:

1. Navigate to “C:\Program Files (x86)\Microsoft Dynamics CRM\Client\” and open the “CrmClient{guid}.config” file in a text editor such as notepad.

2. Insert the following block of XML in the <system.Net> section of the CONFIG file.  

<settings>

     <servicePointManager expect100Continue="false" />

</settings>

3. Open Outlook and the setting will take effect immediately .
