Improving Performance over a Low-Bandwidth Connection

Citrix recommends that you use the latest version of XenApp or XenDesktop on the server and Receiver on the user device.

If you are using a low-bandwidth connection, you can make a number of changes to your Receiver configuration and the way you use Receiver to improve performance.

Changing Your Receiver Configuration

On devices with limited processing power or where limited bandwidth is available, there is a trade-off between performance and functionality. Receiver provides both user and administrator with the ability to choose an acceptable mixture of rich functionality and interactive performance. Making one or more of these changes can reduce the bandwidth that a connection requires and improve performance:
  • Enable SpeedScreen Latency Reduction. SpeedScreen Latency Reduction improves performance over high latency connections by providing instant feedback to the user in response to typed data or mouse clicks.

    User side: Connections > Properties > Connection page

    Server side: SpeedScreen Latency Reduction Manager

  • Enable data compression. Data compression reduces the amount of data transferred across the connection. This requires additional processor resources to compress and decompress the data, but it can increase performance over low-bandwidth connections.

    User side: Connections > Properties > Connection page

    Server side: Citrix Audio Quality and Image Compression policy settings.

  • Enable disk caching. Disk caching stores commonly used bitmaps (images) locally on the user device so that the bitmaps are not transferred over the server connection every time they are needed.

    User side: Connections > Properties > Connection page

  • Reduce the window size. Change the window size to the minimum you can comfortably use.

    User side: Connections > Properties > Window page

    Server side: XenApp Services site > Session Options

  • Reduce the number of colors. Reduce the number of colors to 256.

    User side: Connections > Properties > Window page

    Server side: XenApp Services site > Session Options

  • Reduce sound quality. If audio mapping is enabled, reduce the sound quality to the minimum setting.

    User side: Connections > Properties > Connection page

    Server side: Citrix Audio quality policy setting

Changing Receiver Use

ICA technology is highly optimized and typically does not have high CPU and bandwidth requirements. However, if you are using a very low-bandwidth connection, consider the following to preserve performance:
  • Avoid accessing large files using client drive mapping. When you access a large file with client drive mapping, the file is transferred over the server connection. On slow connections, this may take a long time.
  • Avoid printing large documents on local printers. When you print a document on a local printer, the print file is transferred over the server connection. On slow connections, this may take a long time.
  • Avoid playing multimedia content. Playing multimedia content uses a lot of bandwidth and can cause reduced performance.
