title: Performance of rowNode.setDataValue method
body: <p>I have been evaluating AG Grid component to be used to visualize some streaming data. Unfortunately, client-side model cannot be used since we need to handle big datasets (> 150K rows).  So I focused on server-side and viewport models and found both of them to be quite slow when updating data via rowNode.setDataValue(property, value) calls. It takes about 500ms to update 6 properties of 70 rows. Is it expected to be like that? Is there anything that can be done to make it faster except using rowNode.setData instead?</p>
