If a published application exhibits abnormal behavior after it is configured to use SpeedScreen Latency Reduction, you can use the Add New Application wizard included with SpeedScreen Latency Reduction Manager to adjust latency reduction functionality for the selected application, or all instances of the selected application on the server. To optimize usability of the application, use this wizard to adjust, turn on, or turn off SpeedScreen Latency Reduction for the application.
Note: The application must be running before you can use this wizard to modify existing settings.
To adjust SpeedScreen Latency Reduction for an application
Before you can adjust Speedscreen Latency Reduction for an application, you must add the application to the Speedscreen Latency Reduction Manager.
1. From the Start menu, select All Programs > Citrix > Administration Tools > SpeedScreen Latency Reduction Manager.
2. From the Applications menu of SpeedScreen Latency Reduction Manager, select New to start the wizard and follow the prompts.
3. Use the Define the Application screen to select an application instance on the server. To specify the application, use one of these methods:
• Click the icon at the bottom of the page and drag the pointer onto the window of an application. The application must be running when you select it.
• Click the Browse button and navigate to the application.
4. Specify whether Local Text Echo is enabled or disabled on the application by selecting or clearing the Enable local text echo for this application check box.
For a definition of Local Text Echo, see “Optimizing Keyboard and Mouse Responsiveness” on page 161
5. Specify whether the setting you selected in the previous step should be applied to all instances of the application on the server or just the instance selected.
Test all aspects of an application with Local Text Echo in a non-production environment before enabling it to ensure that the display is acceptable to users.
When you configure SpeedScreen Latency Reduction Manager on a particular server, the settings are saved in the ss3config folder in the Citrix installation directory of that server. You can propagate the settings to other servers by copying this folder and its contents to the same location on the other servers.
Note: If you plan to propagate SpeedScreen Latency Reduction Manager settings to other servers, select Apply settings to all installations of the selected application when configuring Local Text Echo through the wizard. Paths to published applications might differ from one server to another; therefore, applying the settings to all instances of the selected application ensures that the settings apply regardless of where the application is located on the destination server.
To configure latency reduction settings for all applications on a server
1. From the Start menu, select All Programs > Citrix > Administration Tools > SpeedScreen Latency Reduction Manager.
2. From the Application menu, select Server Properties.
The Server Properties dialog box containing existing settings for the selected server appears.
3. Configure the SpeedScreen Latency Reduction settings that you want to be applied to all of the applications on the server. All users connecting to the server benefit from the SpeedScreen options you set here.
Changes made to SpeedScreen Latency Reduction settings at an application level override any server-wide settings.
• Enable local text echo as default for all applications on this server. Select this check box to enable Local Text Echo for all applications on the server.
• Enable mouse click feedback as default for all applications on this server. Select this check box to enable Mouse Click Feedback for all applications on the server.
• Latency threshold times for SpeedScreen (in milliseconds).
Latency threshold times are used when the client device setting for SpeedScreen is set to Auto.
• High latency threshold. Specify a threshold value above which SpeedScreen options should be enabled.
• Low latency threshold. Specify a threshold value below which SpeedScreen options should be disabled.
For a definition of Local Text Echo and Mouse Click Feedback, see
“Optimizing Keyboard and Mouse Responsiveness” on page 161 To configure custom latency reduction settings for an individual application 1. From the Start menu, select All Programs > Citrix > Administration
Tools > SpeedScreen Latency Reduction Manager.
2. In the SpeedScreen Latency Reduction Manager, select the application.
3. From the Application menu, select Properties.
The Application Properties tab containing existing SpeedScreen Latency Reduction settings for the selected application appears. It contains this information:
• Application Name. The application executable name appears here;
for example, Excel.exe.
• Path to Application. The path to the application executable appears here; for example, C:\Microsoft Office\Excel.exe.
4. If desired, configure application settings:
• Disable local text echo for this application. The current setting for Local Text Echo is displayed. Select the check box to disable Local Text Echo for this application. Clear the check box to enable it.
• Limit local text echo for this application. The current Local Text Echo setting for the application appears. Select the check box to limit Local Text Echo functionality for this application, and select the type of text display you need from the drop-down list.
• Forces Speedscreen to treat all input fields in the selected application in native mode. Select the check box if you configure a setting that forces SpeedScreen to treat all input fields in the selected application in native mode.
