These day, I am going to do a performance test on XACML PDP. Actually with WSO2 Identity Server PDP implementation. But main problem me is to define a proper test suit for these testing.
However as a start, I just tried identify the factors that effect for the XACML decision query time.
2. No of Polices and Policy Sets, defined in the PDP
3. Policy Combing Algorithm, used in the PDP
5. Performance of the attribute finders and attribute caching implementation
6. Decision caching implementation
