If the load-balancer is doing true Round Robin, then 1/N requests will
be sent to each server.
If you are not seeing that, then the load-balancer isn't sending the
requests in the first place.

For example, I have an Apache 2.x proxy/balancer here
and /balancer-status is telling me that exactly 1/2 of my requests are
going to each of my 2 back-end servers.

If you could paste some actual numbers, that would help.
