[keycloak-user] Stian: Continuation of Memory Leak Investigation

[Stian Thorgersen]

I've ran with a standard 2.0.0.CR1 server and only changes are adding
"<eviction max-entries="10000" strategy="LRU"/>" to realmVersions cache.

I've now created 10 million users over night and still have steady
throughput of 200 user/sec and memory around 150. What db are you using?
I'm just using default H2 db at the moment,
