+1 on the work, but I question the usefulness of this routing algorithm.
Does reply time (from the backend server)correlate with resource
utilization on the backend server in any but the most contrived cases?
Well, this is the only way the balancer can deduct the load
of the backend server. If the backend server is highly loaded
or with lower performance hardware it response time will be lower
compared to the other participants in the cluster, so it will
get less load, and vice versa.
Of course the ultimate thing would be to actually receive the
feedback from the backend server about its actual CPU/memory
utilization, but thats not protocol independent.
