Clustering

If you are running multiple rippled servers in a single datacenter, you can configure those servers into a cluster to maximize efficiency. Running your rippled servers in a cluster provides the following benefits:

• Clustered rippled servers share the work of cryptography. If one server has verified the authenticity of a message, the other servers in the cluster trust it and do not re-verify.
• Clustered servers share information about peers and API clients that are misbehaving or abusing the network. This makes it harder to attack all servers of the cluster at once.
• Clustered servers always propagate transactions throughout the cluster, even if the transaction does not meet the current load-based transaction fee on some of them.

If you are running a validator as a private peer, Ripple recommends using a cluster of rippled servers as proxy servers.
