So he's evidently young and perhaps a trifle over-enthusiast.  We 
were once too. ;-)

We are not going to get valuable contributions nor help people become 
more valuable to the community by "flaming them into submission".

...and who knows, =properly= done experiment may provide both 
surprises and unexpected insights/benefits.

I agree completely with telling him he needs to get better evidence 
and even with helping him understand how he should go about getting it.

It should be noted that his opposition has not yet done these 
experiments either.  (Else they could just simply point to the 
results that refute Daniel's hypothesis.)

The reality is that a new CPU architecture and multiple new memory 
technologies are part of this discussion.  I certainly do not expect 
them to change the fundamental thinking regarding how to get best 
performance for a DBMS.  OTOH, there are multiple valid reasons to 
give such new stuff a thorough and rigorous experimental shake-down.

ATM, =both= sides of this debate are lacking evidence for their POV.

Let's support getting definitive evidence.  No matter who brings it 
to the table ;-)
