In this area, you can set up additional options to optimize the system's general behavior and its performance.
- Use server redraw:
☑ The Citrix server is responsible for refreshing the screen content.
☐ Do not use server redraw (default)
- Disable Windows alert sounds
☑ Switches off the Windows warning sounds.
☐ The warning sounds remain enabled. (default)
- Backing store
☑ The X Server temporarily stores hidden window content.
☐ Window content is not stored. (default)
- Deferred screen update mode
☑ Enables delayed updates from the local video buffer on the screen. The local video buffer is used if the seamless Windows mode or HDX latency reduction is used.
☐ No delayed update (default)
- Cache size in kB: (default: 1024)
- Minimum bitmap size in bytes: The minimum size of the bitmap files that are to be stored in the cache (default: 1024).
Persistent cache path: The directory where the files are to be stored locally. (default: $ICAROOT/cache)Do not make the cache too big otherwise you run the risk of the thin client having too little storage space for its own system and other applications. You may have no alternative but to equip your thin client with additional RAM.
- Scrolling control: Depending on the speed of your network or the response time of your server, there may be a delay between you letting go of the mouse button on a scroll bar and the scrolling actually stopping (e.g. when using Excel). Changing this value may help (default: 100)
- Audio bandwidth limit in StoreFront sessions
Higher quality requires more network and computing resources.
- Auto reconnect
☑ Automatically attempt to reconnect if connection is terminated (default)
☐ Do not attempt to reconnect.
- Maximum retries: (default: 3)
- Delay in seconds before reconnecting: (default: 30)
- Allow Kerberos passthrough authentication in StoreFront sessions
☑ Kerberos passthrough authentication is allowed. (default)
☐ Kerberos passthrough authentication is not allowed.This point concerns Citrix XenApp in Version 6.5 and older.
- CGP address
- Use server address
- Text input
- Multi-Stream sessions
☑ Support Multi-Stream ICA
☐ Do not support Multi-Stream ICA. (default)
HDX Adaptive Transport over EDT
- UDP with fallback to TCP
- TCP Only - UDP disabled
- UDP without fallback to TCP
Connect to cloud
This parameter must be activated when you are hosting all or a part of your Citrix environment in the cloud.
☑ You can connect to a Citrix application in the cloud.
☐ Connecting to a Citrix application in the cloud is not possible. (default)
