Handling large Shapefiles

We have an App built using ArcObjects that is asked by end users to - on occasion - open large shapefiles.

When these large (400k features) shapefiles are opened, we notice a significant lag in the performance of the application.

We have determined that part of this is due to the Application having to draw all of the features that fall within the full extent. What is the best way to limit the extent of the Map Control prior to drawing anything? Is there a method that we can use to force the extent of the Map control to a small  area prior to drawing anything?
