Perhaps you should try something like:

#declare Block =
mesh {
   triangle{<0.0,0.0,0.0>,<0.0,0.0,1.0>,<1.0,0.0,1.0>}
   triangle{<0.0,0.0,0.0>,<1.0,0.0,0.0>,<1.0,0.0,1.0>}
}

object {Block}
object {Block}
object {Block}
...

This allows POV to use the same mesh data in separate objects. It may 
not cause much of an efficiency increase here, but in meshes with more 
triangles it can make a big difference.

Also, there is nothing wrong with a box having a thickness of 0, 
although I often prefer to avoid all infinitely thin shapes in my scene. 
This probably wouldn't make any difference in memory or speed, though.
