1. In the Registry Editor, navigate to the subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
2. Click Parameters, and then, on the Edit menu, click New.
3. Create a registry entry 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."



Time Period before Closed port becomes available
Create the TCPTimedWaitDelay key at HKLM\System\CurrentControlSet\Services\TPCIP\Parameters as a REG_DWORD value of 30 decimal.


Tracing and Debugging
"Disable. Tracing and debugging are disabled by default and may cause performance issues if enabled. If necessary disable tracing and debugging by configuring the Machine.config and Web.config files as shown in the following sample:


Optimize .NET Threadpool settings
"Modify the machine.config file to reflect the following best practices:
(manually add this parameter and value to the file) maxWorkerThreads - 100
maxIoThreads - 100
maxconnection - 12*n (where n is the number of CPUs)
minFreeThreads - 88*n
minLocalRequestFreeThreads - 76*n
minWorkerThreads - 50
Example of a server with four processors and hyperthreading enabled, these formulas result in the following configuration:



Disable CRM Platform tracing
In the Registry Editor, navigate to the following location and check that the value of the ‘TraceEnabled’ registry key is set to 0 (zero): HKEY_LOCAL_MACHINE Software Microsoft MSCRM
