Note: You can override the selected SpeedScreen mode for the current session by using the Latency Reduction hotkey. See “Configuring Hotkeys” on page 47 for details.

Improving Performance Over a Low-Bandwidth Connection

If you have a low-bandwidth connection, such as a modem, there are a number of changes that you can make to improve performance:

•Change your client configuration. Changing your client configuration can reduce the bandwidth that the ICA protocol requires. See “Changing Your Client Configuration” on page 54.

•Change the way you use the client. See “Changing the Way You Use the Client” on page 55 for ways of reducing the bandwidth required for a high-performance connection by changing working practices.

•Use the latest client. Citrix is continually enhancing and improving performance with each release, and many performance features require the latest client and server software.

Changing Your Client Configuration

On devices with limited processing power, or where limited bandwidth is available, there is a trade-off between performance and functionality. The client provides both user and administrator with the ability to choose an acceptable mixture of rich functionality and interactive performance. Making one or more of the following changes can reduce the bandwidth that your connection requires, and improve performance:

•Allow maximum data compression. Compression reduces the size of the data that is transferred over the connection. See “Compressing Data” on page 51.

•Turn the disk cache on. Disk caching stores commonly used images and fonts locally on the client computer so that they do not have to be transferred over the connection every time they are needed. See “Caching Images” on page 51.

•Turn SpeedScreen Latency Reduction on. SpeedScreen Latency Reduction improves performance over high latency connections by providing instant feedback in response to typed data or mouse clicks. See “Reducing Display Latency” on page 53.
