Improving Microsoft Dynamics CRM Performance Enhancements & Optimization and CRM Server maintenance and improvements

Microsoft Dynamics CRM Performance enhancements, optimisation and maintenance can be divided into three main areas:

– Performance enhancements at Client level: networking issues such cache expiration times, latency and bandwidth
– Optimisation at application level: plugins, sdk code,
– and, improvements at Data layer: Indexes, (physical data layout)

This post is based on Microsoft recommendations and best practices for Microsoft Dynamics CRM 4.0 performance enhancement and improvements.

The first most important enhancement process and action that needs to be taken into account is to always to:  install and setup all the Latest hot fixes and update roll-ups (all CRM 4 updates link – KB article)

Now, let’s go through some of the possible enhancements for each area of those 3 main areas.

Client Level performance enhancement:

– Specify a value from 200 to 300 megabytes of disk space for temporary Internet files
– Web objects cache are usually 3 days by default, change it to make it 15. IIS –>CRM Website ->HTTP header.
– Consider using compression techniques: WAN acceleration appliances have been proved to cause excellent performance enhancements to Microsoft Dynamics CRM 4.0 .
– Make sure that your client machines bypass proxy server if you have one. Proxy servers could delay and affect performance between clients and server machine.
Application server performance enhancement:

– Some .NET code could cause potential issues: Ensure good .net coding practices and avoid bad practices such as memory misuse, improper use (and unessential use) of threading, no resource cleanup, implicit type conversion, Misuse of collections and inefficient loops.
– Increase the reserved port limit. Consider increasing reserved ports to be up to maximum of 5000. Only programs requesting specific ports can use reserved ports. To increase the limit do the following:

1. In the Registry Editor, navigate to the subkey:
2. Click Parameters, and then, on the Edit menu, click New.

3. Create a registry entry by using the following information:
Value Name MaxUserPort
Value Type DWORD
Value data 65534
Valid Range 5000-65534 (decimal)
Default 0x1388 (5000 decimal)
Description Controls the maximum port number that is used when a program requests any available user port from the system. Typically, ephemeral (short-lived) ports are allocated between the values of 1024 and 5000, inclusive.
4. Close the Registry Editor, and then restart the computer to apply the new configuration.

– Always Monitor performance of your Microsoft Windows server. (don’t forget patches, updates, rollups, etc)
– Disable Tracing and debugging on IIS of your production environment as it usually causes performance issues and slows down performance.
– Thread pool settings: Creating threads on a per-request basis and not sharing threads using thread pools can cause performance and scalability bottlenecks for server applications.
– Installing server roles on more than one computer: In Microsoft Dynamics CRM 4.0 Enterprise Edition, you can specify to deploy one or both of the two server role groupings on one computer, or to have each one of them on a separate machine. Microsoft Dynamics CRM server roles are: Application server and platform server server roles.
– Another improvement is to Modifying the default view for entities that potentially has large number of records. In this case, instead of setting the default view to show all Active records, which in some cases can be too many recrods, you should set the default view of such entities to show “My records” only. This way, there will be no pulling of all active records on the server everytime you attempt to view this entity.
Data Layer performance enhancements:

– Row compression results in significant improvement in application performance.

– Page Compression is only good for 80% reduction in space requirements with no considerable change to performance (negligble performance decrease is possible with page compression).

– Consider using Sparce columns.

– Use Transparent Data Encryption.
