If u run multiple haproxys, u're going to be introducing more variables into the mix - specifically, the underlying OS SMP specifics. If you run a single haproxy, u get the benefit of knowing that the code within is already highly tuned for load balancing already - you're in a very well defined (and tested) "box", so to speak (provided you dont have a lot of other stuff running on the same server). So the question is, which do you think is better?
