I think this is caused by the good file caching mechanism of the ffs system. 
What you get seems now to be the transfer speed in the RAM, because the ffs 
cache as much as possible.


The options I used were only -O.

I've done it again with your options and here is the result.

It seems, everything has turned into a little bit better for my system with 
this options then for yours ;)
