[keycloak-user] Performance issues when creating users with keycloak-admin-client

Hello, are there any performance issues known regarding the following method? Keycloak.realm("someRealm").users().create(someUserRepresentation); We want to create a batch of users in a loop. After every tenth user it lasts approximately 10 minutes for the call to return. Is this behavior known or did we miss to configure something? Kind regards Jan Lengenfeld
