What exactly gets slow?  Everything (placing the trees of course, 
parsing the generated trees, rendering) should be roughly proportional 
to the number of objects (rendering even faster) as long as you don't 
exceed memory.

And of course parsing such a file will take some time.  You might be 
able to improve this by storing the numbers with different accuracy 
(normal vectors usually do not require a lot of decimal places).  And 
when you position objects you should not use macros, better calculate a 
matrix and write it to the file.
