Configure Compression

Enabling compression may improve performance where your network connection is limited by low bandwidth.

When remote session services are enabled, session components are set up on a remote computer. This can be on the X client host or on a nearby computer (as shown in this diagram). With this configuration, protocol that passes between the domain node and your workstation is compressed. (Protocol that passes between the client and the domain node is not compressed.)

1 - Workstation running X Manager or X Manager for Domains
2 - Domain node near the X client host running remote session components
3 - X client host

Before you begin

Configure support for remote session services:

If you are connecting from standalone X Manager, see How to Configure a Distributed Session in Standalone Mode.
If you are connecting from X Manager for Domains, see Domain Setup: Improve Performance Over a Slow Network.

To enable compression

Start X Manager or X Manager for Domains.
Select the session definition you will use for this connection. On the General tab, under Remote session services, select any option other than none.

Click the Advanced tab. For Compress protocol to remote X server displays, select one of the following settings:

Dynamic	(Default) Reflection X Advantage measures the bandwidth of data traveling from the protocol router to each remote X server and automatically compresses the protocol when the bandwidth is low enough to be likely to affect performance.
Always	This option may provide better performance where CPU and memory resources are less limiting than bandwidth.
Never	This option may improve performance if bandwidth is less limiting than CPU or memory.
