Yes, that's my entire point.  You can't prove this stuff, you can't say 
that this minor tweak improves performance by X amount, you can't say 
anything definitive about performance until you profile the real world 
application you're dealing with.  To prove my point all I need to do is 
cast some doubt on the authoritativeness of your figures, which I did.  
I presented a number of things which may have affected the results you 
got.  You've come back and disagreed with some of them and thrown some 
more numbers into the mix that you believe support your case, some 
right, some wrong.   At this point though there is no point in us 
continuing to go back and forward over this.  If you want to believe 
that ++i is faster than i++ and that it's worth your while remembering 
that, go right ahead.  I'll happily continue with the process that has 
proven itself time and time again in my work with Java:

1. Think through your design and choose appropriate algorithms.
2. Write clean maintainable code.
3. If the application isn't fast enough, profile it.
4. Fix the performance bottle necks.
5. Go to step 3.
