I do not know LDraw, but I hope any mesh is described as a mesh2
(parsing of mesh{} is kind of exploding parse time as number of
triangles increases (there is a search amongst previous points/vectors
for each new one... ))

There is also some patches somewhere which would cache macro in memory
instead of doing file access. If you have lot of macro in many files, it
might help.

And maybe the obvious: can you have a ramdisk for the scene to parse ?

And to end it: have you check you have not hit the swap of your system ?
