Agreed, I'll change this.

> Issue Type: Improvement
> Affects Versions: 0.11.0
> Reporter: Derek Dagit
> Assignee: Derek Dagit
>
> In the UI, the Topology Page and the Component Page each make a
> getTopologyInfoWithOpts thrift call to nimbus for executor heartbeat data.
> Metrics from this data are then aggregated in by the UI daemon for display.
> When large topologies, with high-connectedness, are viewed in this way, the
> load times for each page can be minutes long. In addition, heap usage by the
> nimbus JVM can grow substantially as data for each executor, component, &
> stream is serialized to be sent to the UI.
