I didn't say that.  What I said is that over a full suite of write 
benchmarks, the effect of changes like this has always averaged out to 
zero.  You should try it sometime.  Then we can have a useful discussion 
of non-trivial results instead of you continuing to tell me I don't 
understand things.
