Summary: [GSS] (5.2.0 patch) Improve SimpleRoleGroup Scalability to Large
Numbers of Roles
Key: SECURITY-962
URL: https://issues.jboss.org/browse/SECURITY-962
Project: PicketBox
Issue Type: Patch
Components: Identity
Reporter: Derek Horton
Assignee: Stefan Guilhen
Fix For: PicketBox_4_9_3.Final
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.
