I'm not a big fan of DSR. DSR was a hack so they can double performance
numbers (it's not a matter of throughput, it's packets per second)
Making modifications to my web/mail servers is not something I want to do.
That's why you get a load balancer. And not all servers support binding
to a bound IP. Some servers you don't have source or support for, and
then you are SOL.
Having the LB in the data path is really the only way to make LBs work right
and if you remove half of that stream, you also lose half of the information.
When L5 and above information is making more and more of a difference, DSR just
makes half of it invisible.
