Serf Convergence Simulator
The graph below shows the expected time to reach various states of convergence depending on the settings which are tunable below the graph. Below the graph, the estimated maximum bandwidth usage is shown per node in kilobits per second.
The default values in the boxes are also the default values that Serf is configured with, where applicable.
Estimated max bandwidth: 0 kbps/node
Gossip Interval
The gossip interval controls how often messages are gossiped to other nodes
