Puma Service tuning

The options configured under the PUMA Service affect the performance characteristics of the internal PUMA layer, the function of which is to build a member object associated with a user’s specific attributes. This is achieved in part by submitting a request to another internal Portal component called WWM. For efficiency, PUMA was designed to initially request a minimum subset of attributes from WMM, which would in most circumstances fulfill most member object requests.

The user.base.attributes property is a comma separated list of attributes that will be requested initially from WMM by PUMA when a user first logs in. The user.minimum.attributes property is a comma-separated list of attributes that will be requested initially from WMM by PUMA. If Portal or a Portlet requests an attribute that is not defined in the list, PUMA is then forced to make a subsequent request for the entire attribute subset. This is somewhat costly in terms of performance, as additional queries to the user data store will result.

You should ensure that both the user.minimum.attributes and group.minimum.attributes
settings contain the attributes deemed necessary for your requirements. If Portal (or a Portlet) requests an attribute that is not present in any of the above lists, PUMA will make a second request to the user registry. However, such a request will actually be for a full attribute set retrieval, from the user registry through WMM.
