Yup, that's exactly what I say: consider running 64 bits, even though
running 32 bits is what most people do.  Is it really necessary to
paraphrase that?

What I'm trying to say is: please do not spread unsupported rumours, 
even if they give you a warm fuzzy feeling.

You state that 

> running 32-bit on a 64-bit system can OFTEN be a performance WIN

but when asked for a reference, you say

> I can't give an actual reference, I'm afraid

...which makes it a rumour.  Please try not to spread rumours,
that does not help anyone :-)
