-------------------------------------------
Summary: Improve SimpleRoleGroup Scalability to Large Numbers of Roles
Key: SECURITY-894
URL: https://issues.jboss.org/browse/SECURITY-894
Project: PicketBox
Issue Type: Patch
Components: Identity
Reporter: Philippe Marschall
Assignee: Stefan Guilhen
During load testing we found out that SimpleRoleGroup does not scale well to large numbers
of roles (200 in our case). The reason for this is that it uses {{ArrayList#contains}}
with scales linearly with the size of the collection. Since the method is called in a loop
the scalability is actually quadratic.
See the following [mailing list
discussion|http://lists.jboss.org/pipermail/wildfly-dev/2015-June/004033....] and the
attached screenshot.
