Citrix Systems 10 Benutzerhandbuch

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.

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.

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.
