I disagree with your statement. I just ran three tests of unions vs. meshs
of triangles and the unions in all three cases parsed and rendered faster.
Meshs seem to only have the advantage of memory optimization when using
multiple copies of the same mesh object.

Triangle object 1 - 200 triangles

union parse   render
       0      22 sec
mesh   0      26 sec

Triangle object 2 - 1000 triangles

      parse   render
union  2      25 sec
mesh   2      30 sec

Triangle object 3 - 6000 triangles

      parse   render
union   9     32 sec
mesh   10     39 sec
