Does it have a way to improve wp-admin/admin-ajax.php?action=upfront_load_editor_grid code?

Hi, I am trying to improve Upfront a little bit more om my site to speed it up. And I have realized that wp-admin/admin-ajax.php?action=upfront_load_editor_grid file takes a while to load. Is it possible to minimize it in some way? Maybe even taking some edition techniques to generate less divs on Upfront editor? Thank you!
