Hi We've been using haproxy for load balancing on Amazon ec2 instances across two different Amazon zones in the same region.
But we are observing a strange phenomena. The servers in the same zone as haproxy are giving less throughput as compared to the servers in the other zone. Though the throughput should be same if haproxy is working on perfect round robin strategy. We are not using any weights for distributing the load, and it should be perfect round robin. But still we are getting different throughput on servers located in different zones. Can someone please elaborate this haproxy behavior? Thanks Himanshu Sahu
