●Client Performance: HP Web Jetadmin provides a significant improvement in application performance over earlier versions. The client application performs many tasks locally to reduce traffic to the server, thus improving client performance. HP Web Jetadmin leverages the client application in many ways to maximize performance.

◦The client application is built on .NET technology, avoiding the need for contacting the server to complete user actions.

◦All graphics are managed by and reside with the client.

◦Notification of change events from the server are performed on an as-needed basis only.

◦Most list operations are performed by the client application and not at the server.

◦Client performance benefits from virtualization because only data needed for display is actually passed from server to local host.

◦All clients share update traffic from a single data set on the server.

◦At times, client performance can be impacted by the settings of either or both network and

HP Web Jetadmin settings. HP Web Jetadmin uses an economical polling pattern when gathering information from devices. If a user interface element that causes HP Web Jetadmin to retrieve information from devices is added, the result may be less than optimal.

●Running Multiple Clients: You can run more than one HP Web Jetadmin client application on a single host, and you might also have multiple client sessions communicating simultaneously to different HP Web Jetadmin server applications. On a single host, you may also run multiple client sessions that are connected to the same HP Web Jetadmin server application.

●Smart Client file cache: The files for the Smart Client application and other Microsoft .NET applications are stored in this file cache. The following are the characteristics of the Smart Client file cache:

◦Files are stored in the following directory: C:\Users\<username>\AppData\Local\Apps\2.0

◦Administrative access on the local machine is not required to install and remove the files and directories.

◦Microsoft .NET Framework imposes a 200 MB limit for the Smart Client file cache.

◦The Smart Client file cache contains the client debug control file and trace log. To manually clear these files, use the following Smart Client cache tool. The files are reloaded during the next run.

Mage.exe –cc Del *.*

●Copy and Paste: In Device Lists , device information can be copied and pasted into other applications. Select one or more rows, click Ctrl-Cor right-click on a device and then select Copy. When pasted, this information is formatted the same way a device list export would be: the first row is column headers and the subsequent rows are the selected devices.

In the Status tab, you can select fields from the device information section and click Ctrl-C.
