When viewing the Monitoring Dashboard, System Status, Last 20 issues and Host status sit there refreshing for 40+ seconds when filtering the dashboard (doesn't matter what options are selected in the filter settings). Just checking Enabled creates this issue.

We only have 296 hosts (13870 items, 3547 triggers) in the system.

As soon as I turn off the Dashboard filter, load times for all widgets goes down to about 3-5 seconds.
