Configuring Connection Settings
These settings let you manage connection speed settings to optimize performance.
To configure connection settings:
- Select the Xconfig file in which you want to configure connection settings and open the Exceed onDemand Xconfig dialog box.
- On the Performance page, select the appropriate connection settings from the Connection area.
You can select from the following:

-
SpeedThis setting lets you specify the speed of your network connection. To optimize performance, Exceed onDemand tunes its behavior according to the setting you select:
- Auto DetectThe proxy detects the speed of the network connection before connecting to a host, and then uses the appropriate mode: fast or slow. To detect speed, a series of round-trip requests are sent between the Exceed onDemand Desktop and the proxy. This process can result in a small delay in startup time, but behavior is automatically tuned to the connection speed, and overall performance is maximized. This is the default setting.

In most cases, the connection speed detection results in the following settings. You can view the results in the log file called ewebhost.log.
Connection Type
|
Auto Detect Result
|
LAN (10 Mbps or higher)
|
Fast
|
WAN (DSL, cable modem, dial-up modem)
|
Slow
Note:
Due to variations in speed that occur with DSL and cable, auto detect results for these connections can also be Fast.
|
- FastThe proxy does not attempt to detect the speed of the connection. Instead, behavior is forced to suit fast connections such as LAN connections. Data compression is minimized with this setting. Startup times are reduced.
Note:
|
|
Do not select this option for WAN connections without setting the Compression option to All Data. |
- SlowThe proxy does not attempt to detect the speed of the connection. All data transferred over the connection is compressed (as is the case if the All Data option is selected in the Compression drop-down list) to minimize bandwidth usage and reduce startup time. For this reason, the Compression drop-down list is dimmed when you select Slow speed. You can select the Slow option for two reasons:
-
-
You know that you are working over a slow connection, such as a dial-up modem, and want to improve connection time.
-
-
or
-
-
You know that you are working over a fast connection but want to conserve bandwidth. In this case, performance may be slightly slower, but there is a significant reduction in bandwidth usage.
-
CompressionSelect the appropriate data compression setting from the Compression drop-down menu:
- All DataCompresses the data stream (all TXP data) between the client desktop and the proxy. Select this option to conserve bandwidth over a fast connection. In this case, performance might be slightly slower, but there is a significant reduction in bandwidth usage.
- Large Data OnlyCompresses only large images in XPutImage and XGetImage requests, and large X font files. The reduction in bandwidth usage is not as large as with the All Data setting, but performance degradation is minimal. This is the default setting.
- NoneNone of the data is compressed. This setting is not recommended for slow connections such as dial-up modems.
Note:

|
If you are running a dynamic X application such as a 3D rendering or 2D animation program, you can improve performance on fast connections by disabling compression and caching. On slow connections, keep the options enabled. |
- Click OK to save changes and return to the previous dialog box or click Apply and select another tab to continue modifying this Xconfig file.
