Long time loading after click Action Modal

Hi, now Im facing the page took long time to load on landing, after click action, after submit. when landing I use ->deferLoading() to make it feel like lazy loading but after landed the update ajax took about 1.5s-2s to load even query was only 50ms and it's loaded 2 times after landed - is it about I have like 13 action modal in page ? how to prevent . - the query was took only 50ms, so I think it's not about queries. - I see huge amount of view that rendered is it about this? how to fix.
