Stefan Matheis (steffkes) commented on SOLR-6395:
-------------------------------------------------
Tim, i had to check the requests we make on the tree view .. there is currently
only one that loads the whole tree information, additional requests happen in
case that the user looks at a entries detail.
If there is a possibility that we can request only one (the specified) level
for the tree .. we could use that to lazy-load nested information, if that
helps improving the performance for larger instances?
> If the overseer queue is large, then the cloud tree view (admin UI) hangs

> Of course, an overseer queue that is backed up is a symptom of bigger issues,
> but if it is, the tree view in the cloud panel becomes almost un-usable,
> presumably because the UI is trying to pull all the overseer queue child
> nodes? Be better to lazily load child nodes when the parent znode tree
> element is opened.
