Hi, I found that the response time of the create realm request increases linearly, from 0.5 second to tens of second when I created hundreds of realms. It perhaps caused by: when I create a new realm(exmpale test), keycloak will add a test-realm client into the admin-realm's client and add test-realm's roles into ADMIN composite role. I test it by using java sdk keycloak-admin-client (1.7.0.Final), datasource: h2/mysql/mongodb. So how many realms does keycloak can support or is there any solution?
