I repeated the same test using a mesh angle of 10.

2.7GB or Ram occupied and 3:55 minutes to load.

Well...I still consider this a long time :)

I know that comparing very different software is a useless thing but....just to give you a info :

the same model loaded into Rhino V6 WIP took about 1:25 minutes to load as a Block entity and with display style as Shaded.
And the rotation of the viewport was many times faster than in Moi.
I thought it was in this way because of the Block, but I have also "exploded" the Block into standard polysurfaces and the viewport performance
was still excellent.

@You : "...At some point here I think I'll be able to do the display meshing part using multiple cores which should help speed up file loading some..."

I think this will change the things a lot!

Thanks :)
