Hi. Thanks for help.
I agree that testing is the easiest way to check. However I hoped that elastic search already have answers about this kind of issues. My query timing are OK, but i wonder maybe elastic search doing better with a lot of small aggregations, or it's doesn't care as they always will have same time to execute. Like time to execute 100 es request to make 1 aggregations at a time === time to execute 1 es request with 100 aggregations in it? What is better for es itself? Thank you.
