Currently all queries to ACL produce a new ACL object: https://github.com/jenkinsci/role-strategy-plugin/blob/6b91d9fa597fb6b6766589556aab4ab5d727368e/src/main/java/com/michelin/cio/hudson/plugins/rolestrategy/RoleMap.java#L164 . It may lead to massive object creation when listing views with big job number.

It would be great to somehow cache objects between calls.
