  • Compression: Reduces the quantity of data transmitted via the ICA session. This in turn reduces network traffic to the detriment of CPU performance. (default: disabled)

    • Enable compression if you connect your server(s) via WAN.
    • Disable this option if you use a relatively low-performance server and only work in one LAN.
  • Persistent cache: Enables caching in the cache memory (configured in the global ICA settings) for each session. (default: disabled)

    Caching image data makes sense if you use a number of ICA sessions but 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 memory for these sessions.
  • Encryption level:
    • Basic
    • RC5 (128 bit - logon only)
    • RC5 (40 bit)
    • RC5 (56 bit)
    • RC5 (128 bit)
    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 degree of encryption.
  • Client audio:

    ☑ Transfer system sounds and audio output from applications to the thin client. (default)

  • Audio bandwith limit:
    • High
    • Medium
    • Low
    The higher the level of audio quality you select, the more bandwidth is needed for transferring audio data.

Speedscreen Latency Reduction

  • Mouse click feedback: The mouse pointer immediately turns into an hourglass symbol, thus providing visual feedback in response to a mouse click.
    • Automatic
    • Off
    • On
  • Local text echo: Displays the text entered more quickly.
    • Automatic: If you are not sure how fast the connection is.
    • 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.
