You are comparing the two products and arguing that as OpenERP is more 
widespread it is better designed. I'm showing you that is not the case. It is 
not for functional design and it is not for performance considerations. (Which 
does not mean Tryton is always faster).

Have you shown evidence that this is a problem? Have you seen the performance 
limitations of OpenERP orm? Have you considered that given that OpenERP ORM is 
inferior it they may be adding fields as a workaround?

I don't understand the argument. You talk about queries and RAD at the same 
time. RAD alllows you to work without worrying about queries to the database 
because the ORM does that for you.

The problem is that you're suggesting there are performance issues yet to be 
proved. Instead of showing real world examples of the issue you compare with a 
product that you expect to be better performant than Tryton, but just let me 
put you an example:

Although OpenERP claims to have very large installs it cannot close stock move 
periods [1]. Can you imagine that each time a user accesses the list of 
products the ERP is querying all the moves of the given product with their 
unit of measure and making the conversion? That's what OpenERP does.

So again, saying OpenERP does something in a given way is not an argument, 
because it is not necessarily based on experience.
