Hello,
I'm deploying Keycloak 20 using the Keycloak Operator and trying to connect to a remote infinispan machine. It is a single machine that I started up with default configuration.
When I start up everything works but when I try to perform stress tests, then the infinispan get crazy and use whatever CPUs has. It was able to use 16 full cores and still fail to handle requests... (i was performing 50users/sec for 10 minutes).

Any suggestion on how tune infinispan or if I'm doing something wrong ?

This is my keycloak resource:

apiVersion: k8s.keycloak.org/v2alpha1
kind: Keycloak
metadata:
  name: example-kc
spec:
  instances: 1
  ingress:
    enabled: false
  hostname:
    hostname: my-keycloak.com
  http:
    httpEnabled: true
    httpPort: 8080
  transaction:
    xaEnabled: true
  db:
    passwordSecret:
      key: password
      name: keycloak-db-secret
    usernameSecret:
      key: username
      name:  keycloak-db-secret
    url: jdbc:postgresql://my-host:6000,my-host-2:6604/keycloak
    vendor: postgres

Thank you,
