 From the Land of Cheese:
Where the longer parse time comes from is in the while loop distributing 
the cubes. This loop resides in a separate inc file. and looks like this:

//==========================================================
#local R1 = seed(1929);
#local R2 = seed(9732);
#local R3 = seed(6493);
#local N1 = 4000;
#local I  = 0;

#while (I <= N1)
   #local Start = VRand_In_Obj(RocksBox, R1);
   #local Norm = <0, 0, 0>;
   #local RockPos = trace(Landscape, Start, -y, Norm);
   #declare Visible = IsObjectVisible(RockPos)
   #if (Visible)
     #if (vdot(Norm, y)>0.8 & RockPos.y<50.0*(0.8+rand(R1)*0.4) & 
RockF(RockPos.x,RockPos.y,RockPos.z)<0.5+rand(R1)*0.1 & RockPos.y>0 )
       object {Rock
         //scale (RockPos.y+(1/RockPos.y))*RRand(0.9, 1.1, R2)
         scale RockPos.y*RRand(0.9, 1.1, R2)
         rotate RRand(-180, 180, R3)
         translate RockPos
       }
       #if (mod(I, N1/10) = 0)
         #debug concat(" Rocks: ", str(I,5,0), "\n")
       #end
       #local I = I + 1;
     #end  //slope & altitude
   #end  //Visible
#end
//==========================================================

Otherwise, parse time is about equal between versions when the loop is 
disabled.
