Comment (by pnorman):
The export call can't take advantage of any tile caching, either on the
edge cache servers or the render servers. Some back of the napkin
calculations put it as about as expensive as 5000 tiles in terms of server
resources.
The [http://wiki.openstreetmap.org/wiki/Tile_usage_policy tile usage
policy] covers the export call.
Aside from all of this if the server load is above a certain point the
export call shuts down to prioritize tile rendering.
That being said, there probably is room for UI enhancements so that you
know where you're rendering.
