What do you use to distribute the load/requests between the set of servers?
Without knowing any other details/metrics this would just indicate that the
balancing mechanism/solution doesn't do the job the way you would expect.



Just for example a simple dns roundrobin while in long term works fine (the
requests are distributed somewhat eventy) still the load on the first
entry/server is always (a bit) higher.
