When running 4D on a Windows Server OS (e.g. Windows Server 2003 or Windows Server 2008) there are some recommended "Performance settings" to use:

• Windows Processor Scheduling: set to “Programs” instead of “background processes”.


• Windows Memory: set to “Programs” instead of “System Cache”.


• Windows Page File: set to “System Managed Size” instead of “Custom Size”.

The location for these settings may vary based on the OS but the key settings to look for are named above.

They can typically be found following these steps:

1. Click Start, click Run, and then type "sysdm.cpl" in the Run box.


2. In the System Properties dialog box, click the Advanced tab, and then click Settings under Performance.

These recommendations apply to all 4D applications (single-user and server) wether running under a user account or as a service.
