[keycloak-user] Poor response time for User REST API

Hi all, I have ~4k users imported in my (postgres) database, when I go for GET /{realm}/users/ For max=100 (default) it takes about 20-22s to respond (60kb document). For max=20, I still get 4s response time, which is kinda... not ideal. I’m not sure if those response time are normal, and if not why is this so slow ? I’m guessing this overhead is caused by the JSON response, I tried on the database (>20ms). -> is there a way to reduce the JSON data response produced by Keycloak ? I only need usernames. I didnt find anything on the docs, I tried ?fields=username in query param, sadly it doesn’t work. In case you’re wondering why I do that, I want to use an auto-complete on my app, with usernames.) Thanks for reading. Cédric.
