Solution
The performance of the servers can be improved by tuning certain parameters. WorkerThreads need to be
introduced.WorkerThreads exist in a pool and perform all the work associated with request processing. By
default, they are set to ‘0’. For them to operate efficiently, the registry needs to be modified.
To modify the registry, perform the following steps:
1. Click Start, and then select Run.
The Run dialog box appears.
2. Enter regedit.
The Registry Editor window appears.
3. Browse to the following path:
HKLM\System\CurrentControlSet\Control\Session
Manager\Executive\(REG_DWORD).
4. Double-click AdditionalCriticalWorkerThreads from the list in the description field of the window.
The Edit DWORD Value dialog box appears.
5. Select any one of the Base options as required.
6. Enter Value data according to your selected Base option.
For example, if you want to enter 10k as the value, do the following:
For Hexadecimal, enter 186a0.
For Decimal, enter 100000.
For more information on how to decide the optimal number of WorkerThreads for the Value data field, refer
to “Deciding the optimal number of WorkerThreads” on page 4.
7. Click OK.
8. Double-click AdditionalDelayedWorkerThreads in the list in the description field of the window.
The Edit DWORD Value dialog box appears.
9. In the Edit DWORD Value dialog box, repeat steps 5 through 7.
10. Reboot the system.
The registry modifications take effect.
