Hey Richard for a large level, a few things will help with render speed:
using frustumClipping (see the demo here for details on use: http://www.infiniteturtles.co.uk/blog/away3d-23-released) using the fog filter (does a similar job to the frustum but culls objects after a certain distance where they can no longer be seen) if you split your level into containers (ie. use objectcontainer3d for each room, say), then just turning on object culling should improve things. this is done in the default clipping property for the view: view.clipping.objectCulling = true; and will remove all objects outside the viewable area from the render loop before vertex projection, the single biggest saving. hth!
