[keycloak-user] Theoretical max number of clients Kecyloak can handle

Hi All, What's the theoretical max number of clients Keycloak can handle efficiently? I'm doing some tests where I created around 10000 clients (saml & openid, all under the same realm) and now every operation that has to do with clients (list them, create new one, get one by ID, etc) became extremely slow and sometimes they even timeout. The other API endpoints seem to perform just fine. I'm using 4.6.0.Final and MySQL DB as a data store. Are there some options I can tweak to improve the performance with a few thousands clients (ideally around 50K)? Will postgres perform better? Thanks a lot, Daniel.
