[keycloak-user] Load testing and performance

[Marko Strukelj]

The default hashing iterations is fairly high to safeguard for the case of
a leaked database.

See:
http://www.keycloak.org/docs/latest/server_admin/topics/threat/password-db-compromised.html

If you are comfortable with decreasing the number of iterations that's
definitely the first thing to try to increase performance.
