8.2. Optimized Replication Mode Usage
Replication mode is used for state sharing across a cluster. However, the cluster performance is optimal only when the target cluster contains less than ten servers.
In larger clusters, the fact that a large number of replication messages must be transmitted results in reduced performance.
Red Hat JBoss Data Grid can be configured to use UDP multicast, which improves performance to a limited degree for larger clusters.
