want to start here before opening a "bug" because it is quite possible environment/config specific.

we've noticed 15-20 second latency querying auth/admin/realms/realm/groups/<group_id>/members. group size does not appear to be a factor, i can make a test group with 5 members and get the same result as larger groups (largest is only ~50 members).

first noticed on 13.x but have validated the same happens after upgrading to 15.x (do not want to jump to 16+ since the config change is dramatic enough we're instead investing in migrating to quarkus). resource monitoring for containers/DB look fine, nothing in slow query log, nothing obvious in app logs.

i can open a bug if it's a better avenue, but wondered if anyone has seen similar behavior or can think of tuning which might help.

thank you in advance.
