Select Enable, set parameters and click Configure.
Studies arriving on a server get registered in the database and stored on the disk. By default, they are not processed for viewing until a workstation requests the data. When such a request occurs, the server processes the data by extracting pixel data, creating thumbnail images, building compressed data files, etc. If the user initiated the request to open a specific study before a prefetch took place, this processing is done while the user waits. To help improve download performance, the server can preprocess the data before any workstation requests it using the Compress Action feature.
The Compress Action is configurable on the Other Lists page. Since it is a system action, it is best to create it as the system administration, and attach it to the @system user. Follow these steps to set up this action:
Create a filter identifying which studies you want to preprocess.
Go to the Other Lists page, and find the new filter on the list.
Under Compress, click the button to display the Compress Action configuration window.
Check the Enable box to enable the action.
Check the Apply to Current Content box if you want the server to process all the data on the current worklist (not recommended). The Scheduling option instructs the server when to process the data (usually immediately upon arrival).
Click the Configure button to activate the action.
