[keycloak-user] Keycloak Unable to Handle Heavy Load

Hi, We've been doing some load tests of our services, and we've found that when we raise the traffic rate to about 50 logins per second (with a roughly similar rate of logouts) we kill our Keycloak instances after just a few minutes. What are the normal recommended specs for a Keycloak instance to be able to handle such a load? We're running three instances of Keycloak in AWS (c4.large instances) with a db.t2.medium database. The CPU is Intel Xeon E5-2666 v3 dual core and the instances have 4GB memory with 2GB allocated to Keycloak. Regards, Scott
