Displaying large-ish json result sets perform much worse, at least in some cases, than in the old UI. In one specific example a result that contained a json list of 577 entries totaling around 800KB in size completely hung a browser when trying to expand one of the collapsed sections of results (the data is all initially collapsed in chunks like 0-100, 101-200, etc). This same data appeared to load just fine in the old UI.
