If you select 'disabled' as the option in the auto-refresh control on the dashboard, the underlying calls to refresh the stats actually get called constantly. This is happening because the option value in the picklist is set as 0 and that is passed directly in as the interval for the setTimeout call. This causes it to refresh as fast as possible.
You can see this below by the stream of requests made to the workers endpoint
