While talking about smoothing you must also consider the quality of the smoothing.
You can take some kind of really GOOD smothing at the cost of loading time, or just ignore smoothing having short timings.
In the middle you can have some kind of deals with these parameters...

In SR3DBuilder the 4186.dat part loads in 3.5 seconds on a Centrino 2 2GHz processor and the quality is good enough compromise.

I can give some useful hints about performance on that part:
- using indexed primitives reduces from about 330.000 vertex to about 110.000
- caching already optimized parts in memory allows loading the same part in less then 0.1 sec
- to averate the normals in a vertex I consider the angle between the current vertex normal already computed and the new one I'm going to test. If the angle between them is <45° then the new normal value will be averaged, otherwise a new vertex in the same position is added with the new normal value. This is not the best quality in some cases (part 32197), but is good enough in most of them
