Upstream performances: what if one node only ?

Hi all,

I am wondering about the possible extra-cost of using a single-node 
upstream into proxy_pass compared with  'proxy_pass host' directly.
I need to automate application servers move, and find convenient to update 
upstream definitions only (defined into dedicated files).


upstream upOne {
    server somehost;
proxy_pass upOne;


proxy_pass somehost;

Is solution1 more time-consuming than solution2 at run-time ?

Many thanks for your advises !
