How to improve the rendering efficiency in ArcGIS Engine?

Discussion created by nied-esrichina-com-cn-esridist on Dec 5, 2012
Hi all,

I'm in a development project by using VS2010(C#) + AE10.0, one of the basic functions is reading data from a fileGDB and displaying in MapControl. There are Representations in each FeatureClass.

When i use some tools such as Zoomin\Zoomout\Pan ,i have to wait.... because the map is refresh slowly.
how to improve ?
