The health dashboard pulls multiple tests over multiple suites over multiple platforms. This is done by pulling all signatures for a framework, but this takes time to deliver.
Once acquired, the dashboard will filter out all test/suite/platform combinations required, and then request the signatures that matched.
Maybe the result of each framework can be cached (daily) will may make it faster. Maybe adding an option to filter by
suite will reduce the size of the response which may make it faster.
