How to handle datasource performance in multifield

I found that multifield seems to query the datasource every time when rendering data, which affects performance, is there a way to handle it?

You can do it client side as well.

Use hidden field to store the authored multifield item dropdown value and set the drop from json response on dialog load.

Client side has flexibility to improve the performance by populating the drop downs items once(byXHR call) and append drop down items to each multifield item and set the selected value.
