I think this assertion is content-free.  What you care about is 
the performance of the whole system.  What proportion of that
performance is due to the delays in pumping the RPC messages
back and forth, and which proportion is consumed by business
logic at the endpoints of the transaction? When somebody
does some quantitative work showing that in a significant
real-world application, the number is high enough to be a 
problem worth addressing, then it's worth addressing.  

This kind of thinking goes on all over the place.  I call it
the "junior-engineer-deciding-to-code-it-in-assembler-to-make-
it-faster-without-measuring-first" fallacy.  -Tim
