General Performance Related Settings

Whether you are using graphics intensive applications or streaming media across RDP, some configurations can be applied to provide performance benefits in your environment:

• Display driver optimization – this is probably the most important component, particularly on the Windows CE platforms that tend to have a lot less CPU power than their desktop counterparts. The display "device driver interface" we provide in Windows CE uses only the basic graphics engine functions; where software acceleration is provided through emulation libraries, and hardware acceleration is limited to two-dimensional graphics operations. If at all possible, hardware acceleration should be used.

• Ensure that your video and network card drivers are up to date based on the manufacturer’s recommendations.

• Enable bitmap caching in your RDP session. This can result in some significant bandwidth savings and can also improve the refresh speed. However, this does not mean that graphics intensive applications will run at the same performance level as they would in a non-RDP session.

• Understanding how font exchange works can also lead to some opportunities for performance improvements. Font exchanges occur between the client and server to determine which common system fonts are installed. The client notifies the Terminal Server of all installed system fonts to enable faster text rendering during an RDP session. When the Terminal Server knows what fonts the client has available, passing compressed fonts and Unicode character strings rather than larger bitmaps to the client can save network bandwidth

• If network bandwidth is not as much of a concern, you can increase the frame rate on the client side via a registry modification.
