<h1>Serf Convergence Simulator</h1>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
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 <em>kilobits</em>
|
||
|
|
per second.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
The default values in the boxes are also the default values that Serf
|
||
|
|
is configured with, where applicable.
