Re: [keycloak-user] Keycloak OAuth High CPU usage
Creating tokes are expected to be a bit CPU intensive as they need to be
signed. When you say you try to generate tokens for 10-20 users are you
doing performance tests and having 10-20 threads generating tokens? It
shouldn't make any difference if you have 10 or if you have 200 users, it's
the total number of tokens that can be generated that's an issue. Having
200 concurrent users with a access token timeout of 60 seconds should mean
that you need to be able to generate roughly 200/60 tokens = 3.3 tokens/sec.

Hi All,
I am using Keycloak 1.9.3 with default configuration. Keycloak server is
installed on RHEL 6.5 virtual image with 4 CPU , 8 GB RAM and java version
is jdk1.8.0_73 We are trying to use keycloak as a OAuth provider. But when
we try and generate token(http:///auth/realms/master/protocol/openid-connect/token)
for more than 10-20 users the server gets too slow and cpu usage goes over
100%.
Any pointers on how to improve performance of keycloak OAuth provider. We
need to support at least 200 concurrent users.
Thanks, Vaibhav
