[keycloak-user] Keycloak performance on Kubernetes

Hi, For my portal config I have a Keycloak cluster running in a Docker container deployed with Kubernetes/Azure. Database is postgres (4 cores). I am performance testing by using JMeter to get response times for a POST to /auth/realms/(domain)/login-actions. Overall I'm not seeing very good results: Threads/Response (ms) 200/5009 400/7283 600/10065 I need to support up to 2500 concurrent logins (threads) and realistically response time should be less than 5 seconds. When I run the tests the DB utilization is low. I have tried the following but response times are still fairly slow. 1. Add 3 additional keycloak pods to Kubernetes (result: small improvement in response times) 2. Bump up CPU on keycloak pods (CPU was spiking during tests, but memory usage fairly low) 3. Investigate Azure App Gateway usage (not an issue) I'm running out of ideas now, how can I get Keycloak to handle more logins with better response times? Thanks for any help. Tim
