| No. | Metric | Description |
|---|---|---|
| 1 | Single Threaded Response Time | Measure the execution time for onset and abatement in each use case with only a single policy executing |
| 2 | Single Threaded CPU Usage | CPU Usage for each use case when executing alone |
| 3 | Single Threaded Memory Usage | Memory Usage for each use case when executing alone |
| 4 | Maximum Simultaneous Executions | Measure the maximum number of simultaneous policy executions that can be achieved whilst maintaining system stability and resource utilization |
| 5 | Multi Threaded Response Time | Measure the execution time for onset and abatement in each use case when multiple threads are injecting ONSET events simultaneously |
| 6 | Multi Threaded CPU Usage | CPU Usage for each use case when multiple threads are injecting ONSET events simultaneously |
| 7 | Multi Threaded Memory Usage | Memory Usage for each use case when multiple threads are injecting ONSET events simultaneously |
| 8 | Installation Footprint | The requirements of the ONAP Policy Framework installation in terms of VM resources including the amount of disk space required for the database and for logs. |
Based on the results of the tests, performance of the PDP-D is satisfactory. Should the load increase to the point where performance becomes an issue, then additional PDP-D's can be added; this is already supported and does not require any code changes. As a result, PDP-D satisfies both level 2 and level 3 performance requirements. Additional testing must be done to determine level 0-3 conformance for the other policy components (e.g., PDP-X).
