Hi Liming,
Yes, with this change, the performance is better than before.
Especially for the big formset with lots of configuration, it has better use
experience when loading the formset to display.
Could you help review this patch? Thanks.
Thanks,
Dandan

Have you collected the performance data for this enhancement? Is the updated
