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.
