[keycloak-user] Keycloak get access token performance test encounter out of memory

[Pedro Igor Silva]

Hi,

Ideally, you should configure your JVM accordingly with the load you are
expecting/testing. I would suggest you to try/compare different results
with different settings before reporting any performance issue. If running
in a docker container, check your JVM ergonomics configuration.

Regards.
