A quick look at both Wings and Blender versions tells me a few things.

I can grab information from the Wings version that will make those a tiny bit faster to process. Basically? Since the counts of faces, verts, and such are listed? I don't have to run a loop to count all that on Wings files.

Blender files I'll have to do a loop just to count the stuff.
Probably won't be able to notice it but annoying none the less.

3DMax files also don't need that extra 'Blender' loop.

Blender files you sent seem to show a 'Better' way to organize faces so may reduce sort times. Going to be interesting to see the times for both.
Again it will probably be so fast one really won't notice!


Ahh. Wings also does not list a Normals or texture count so a partial count loop is needed.

I'd also check your settings for Wings to see if you can reduce the number of output to 6 digits.
