Product: PerformanceGuard — a separate CapaSystems product; do not apply this page to any other.

The PerformanceGuard services—the Frontend server, Backend Server and Web Server services—are allocated a certain amount of memory (by default a minimum of 2048 MB and a maximum of 4096 MB).  
If you experience performance problems, and you have sufficient memory available, you can allocate more memory to each of the services in Windows' Registry Editor:

1. On the computer on which the required service in installed, click **Start**, type regedit and press ENTER.
2. Expand HKEY\_LOCAL\_MACHINE/SOFTWARE/Wow6432Node/Apache Software Foundation/Procrun 2.0 and then expand the folder that represents the required service: **pgbackend**, **pgdisplay** (that is the Web Server service) or **pgfrontend**. Then expand the **Java** folder.
3. The element **JvmMs** controls the minimum memory usage of the service. **JvmMx** controls the maximum memory usage of the service, so it's typically this element that you want to modify.  
     
   Right-click the required element and select **Modify...**
4. Overwrite the number in the **Value data** field with the required number. Note that you can view the number in hexadecimal as well as decimal format.![](/attachments/performanceguard/aecef264-c555-4538-a3c3-f609a7a2ce30.png)
5. Click **OK**. Repeat as required for the other services.
