How do I reduce the network traffic in a clustered environment?
If you use the default config, and replace FD with FD_SOCK, then traffic will be null when there is no data between the nodes (e.g. replication messages). Note however, that this is not recommended. We actually recommend using both FD and FD_SOCK together. FD does not generate a large amount of traffic — one point-to-point packet from each node to its neighbor every FD.timeout ms. Depending on what AS version you are using, the default FD.timeout setting is 2500 or 10000; a packet per node every few seconds is not a lot of traffic.
