  • Compression:

    Data compression reduces the amount of data transferred via the ICA session. This in turn reduces network traffic to the detriment of CPU performance. Compression should be used when connecting the server via WAN.

    The data to be transmitted will not be compressed. This setting is suitable when using relatively low-performance servers and when working in a LAN.

  • Persistent Cache Enabled

    The image data will be cached. This makes sense when using a number of ICA sessions if only one or two sessions are critical with regards to network bandwidth or are used heavily during the day. In this case, you should reserve the cache space for these sessions.

    The image data will not be cached.

  • Client Drive Mapping

    The local drives will be available in the session.

    The local drives will not be available in the session.

  • Encryption Level: Encryption increases the security of your ICA connection. Basic encryption is enabled by default. You should therefore ensure that the Citrix server supports RC5 encryption before you select a higher level of encryption.
  • Client Audio

    System sounds and audio output from your applications will be transferred to the thin client and played back via the connected loudspeakers. The higher the level of audio quality you select, the more bandwidth is needed for transferring audio data.

    No system sounds and audio output will be transferred to the thin client.

Speedscreen latency reduction

Improves the performance of high-latency connections by allowing the client to react immediately to keyboard entries or mouse clicks. This gives users the feeling that they are using a normal PC.

Speedscreen only works if the function was enabled and configured on the Citrix server beforehand.


  • Mouse click feedback: Visual feedback in response to a mouse click – an hourglass symbol appears immediately.
    • Off
    • On
    • Automatic
  • Local Text Echo: Displays the text entered more quickly. This avoids latencies within the network. Select a mode from the drop-down list:
    • Off: For faster connections (connection via a LAN)
    • On: For slower connections (connection via WAN) in order to reduce the delay between the user entering text and the text being displayed on the screen.
    • Automatic: If you are not sure how fast the connection is
