Estimate graphics' performance

Use the Graphics Performance Index (GPI) window to view estimated performance statistics of a graphic you are building or editing.

The Graphics Performance Index window can also be viewed if using the Symbol Wizard in Preview mode, and for graphics currently in a non-editable state.

To estimate graphic performance using the Graphics Performance Index

1. Do any of the following in the Industrial Graphic Editor:

   • On the Graphic menu, click Graphics Performance Index.

     

   • Click the Graphics Performance Index icon on the toolbar.

   • Click the GPI: label in the status bar.

   • Press Ctrl+P on your keyboard.

   • Press P on your keyboard if the Graphics menu is open.

   The Graphics Performance Index window appears.

   

   The GPI rating appears in the upper left corner of the Graphics Performance Index window. This calculation is a figure in the range from 0 to 5, based on the type and number of components included in the graphic. A rating of 5 indicates a graphic call up time less than 1 second. See Understand GPI rating calculations for details about how the GPI rating is calculated.

The GPI calculation is based on results from an ideal environment in which required subscriptions are made to an engine running on scan and appropriate references are established.

2. Click the Details button to expand the window. A list displays showing rows of details for component types in the graphic that are greater than 0 in size. These details are as follows:

   Column Header	Relevance
   Description	Component type
   Count	Number of items comprising the component type
   Impact Score	Call up time in milliseconds for the component type

   Rows are sorted in descending order by Impact Score. You can re-sort rows by clicking the designated column header.

3. After reviewing the contents, click OK. You can edit the graphic and test the GPI again using this tool.

Note: You can also estimate the GPI programmatically using the IGraphicAccess3 API. For more information, see Implementing the GraphicAccess3 API.
