Hi Keycloak Team , We are evaluating to use in production and have 2) questions 1) Any information on Keycloak benchmarks would help us decide what Hardware we will need for example 1 Wildfly/Keycloak server with 4 cores CPU with 8GB memory and 1 separate Mysql DB with 4 cores CPU with 8GB with JDBC data connection pooling set to 30 connections say for example can handle ?????? concurrent user longings . 2) What server-cache is used and what control will we have like configuration options other than maxSize Also what unit is maxSize memory in ? Docs Reference : http://keycloak.github.io/docs/userguide/html/server_cache.html Thanks again and Great work with Keycloak G.Leon
