> The ZooInspector tool performs well when connecting to a Zookeeper cluster on the same host it is being run on or to a very close host (network-wise). However, when run against a Zookeeper cluster that is remote (such as one running in the cloud), the tool exhibits very high latency. In my experience, at worst it can takes up to 20-30 seconds between the time a node is expanded and the time the UI is updated.
> Upon brief inspection, this seems to be due to network calls to Zookeeper being made from the rendering thread (though this is not entirely clear).
> I will (hopefully) be attempting to create a pull request to remedy this issue, but I wanted to report it first.
