- Configuring XenApp Acceleration
- Optimizing Chrome and HTML5 versions of Citrix Receiver
- Deployment Scenarios
XenApp acceleration applies to both the ICA and CGP protocols within XenApp. The CloudBridge appliances, XenApp servers, and XenApp clients provide cooperative acceleration of XenApp connections, providing substantial speedup compared to XenApp alone. This cooperation requires up-to-date versions of all three components.
XenApp compression dynamically switches between memory based compression for interactive channels (such as mouse, keyboard, and screen data) and disk based compression for bulk tasks (such as file transfers and print jobs). Compression ratios increase as compression history fills, increasing the amount of data that can be matched against new data. XenApp compression provides several times as much data reduction as does unassisted XenApp, often exceeding 50:1 on repetitive bulk transfers such as printing or saving successive versions of the same document.
XenApp compression achieves high link utilization without congestion, by preventing users from interfering with each other.
HKLM\System\CurrentControlSet\Control\Citrix\WanScaler\EnableForSecureIca = 1 HKLM\System\CurrentControlSet\Control\Citrix\WanScaler\EnableWanScalerOptimization = 1 HKLM\System\CurrentControlSet\Control\Citrix\WanScaler\UchBehavior = 2
These are all DWORD values.
After you start XenApp sessions over the accelerated link, accelerated ICA connections should appear on the appliance’s Monitoring: Connections page. A compression ratio of greater than 1:1 indicates that compression is taking place.
