> When a search for a dag returns no results the system still makes 4 ajax calls to: task_stats,
dag_stats, last_dagruns and blocked which by default return the entire state of the system
which is discarded and not used.
> On systems with a large amount of dags and task meta data this results in an incredibly
slow loading page.
