> On a cluster with atleast 100 hosts, clicking on the background ops button (beside cluster name) takes 3-4s for the dialog to come up. Stop like 2 services (which themselves launch this dialog). Then clicking on the same background ops button takes like >90s to launch.
> The CPU is pegged at 100%, and Chrome warns multiple times to kill the page.
