Policy Drools PDP component
~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Both the Performance and the Stability tests were executed against a default ONAP installation in the PFPP tenant, from an independent VM running the jmeter tool to inject the load.
+
+General Setup
+*************
+
+The kubernetes installation allocated all policy components in the same worker node VM and some additional ones. The worker VM hosting the policy components has the
+following spec:
+
+- 16GB RAM
+- 8 VCPU
+- 160GB Ephemeral Disk
+
+The standalone VM designated to run jmeter has the same configuration and was only
+used to run this tool allocating 12G of heap memory to the jmeter tool.
+
+Other ONAP components used during the estability tests are:
+
+- Policy XACML PDP to process guard queries for each transaction.
+- DMaaP to carry PDP-D and jmeter initiated traffic to complete transactions.
+- Policy API to create (and delete at the end of the tests) policies for each
+ scenario under test.
+- Policy PAP to deploy (and undeploy at the end of the tests) policies for each scenario under test.
+
+The following components are simulated during the tests.
+
+- SO actor for the vDNS use case.
+- APPC responses for the vCPE and vFW use cases.
+- AAI to answer queries for the usecases under test.
+
+In order to restrict APPC responses to just the jmeter too driving all transactions,
+the APPC component was disabled.
+
+SO, and AAI actors were simulated internally within the PDP-D by enabling the
+feature-controlloop-utils previous to run the tests.

+
+Stability Test of Policy PDP-D
+******************************
+
+The 72 hour stability test happened in parallel with the estability run of the API component.
+
+.. code-block:: bash
+
+ small:
+ limits:
+ cpu: 1
+ memory: 4Gi
+ requests:
+ cpu: 100m
+ memory: 1Gi
+
+Approximately 3.75G heap was allocated to the PDP-D JVM at initialization.
+
+Worker Node performance
+=======================
+
+The VM named onap-k8s-07 was monitored for the duration of the two parallel
+stability runs. The table below show the usage ranges:
+
+.. code-block:: bash
+
+ NAME CPU(cores) CPU% MEMORY(bytes) MEMORY%
+ onap-k8s-07 <=1374m <=20% <=10643Mi <=66%
+
+PDP-D performance
+=================
+
+The PDP-D was monitored during the run an stayed below the following ranges:
+
+.. code-block:: bash
+
+ NAME CPU(cores) MEMORY(bytes)
+ dev-drools-0 <=142m 684Mi
+
+Garbagge collection was monitored without detecting any major spike.
+
+The following use cases were tested:
+
+- vCPE
+- vDNS
+- vFirewall
+
+For 72 hours the following 5 scenarios were run in parallel:
+
+- vCPE success scenario
+- vCPE failure scenario (failure returned by simulated APPC recipient through DMaaP).
+- vDNS success scenario.
+- vDNS failure scenario.
+- vFirewall success scenario.
+
+Five threads, one for each scenario described above, push the traffic back to back
+with no pauses.
+
+All transactions completed successfully as expected in each scenario.
+
+The command executed was
+
+.. code-block:: bash
+
+ jmeter -n -t /home/ubuntu/jhh/s3p.jmx > /dev/null 2>&1
+
+The results were computed by taking the ellapsed time from the audit.log
+(this log reports all end to end transactions, marking the start, end, and
+ellapsed times).
+
+The count reflects the number of successful transactions as expected in the
+use case, as well as the average, standard deviation, and max/min. An histogram
+of the response times have been added as a visual indication on the most common transaction times.
