+Policy Clamp Controlloop
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Both the Performance and the Stability tests were executed by performing requests
+against controlloop components installed as docker images in local environment.
+
+Setup Details
++++++++++++++
+
+- Controlloop runtime component docker image is started and running.
+- Participant docker images policy-clamp-cl-pf-ppnt, policy-clamp-cl-http-ppnt, policy-clamp-cl-k8s-ppnt are started and running.
+- Dmaap simulator for communication between components.
+- mariadb docker container for policy and controlloop database.
+- policy-api for communication between policy participant and policy-framework
+- Both tests were run via jMeter, which was installed on a separate VM.
+
+Stability Test of Controlloop components
+++++++++++++++++++++++++++++++++++++++++
+
+Test Plan
+---------
+The 72 hours stability test ran the following steps sequentially in a single threaded loop.
+
+- **Create Policy defaultDomain** - creates an operational policy using policy/api component
+- **Delete Policy sampleDomain** - deletes the operational policy sampleDomain using policy/api component
+- **Commission Contorlloop definition** - commissions the controlloop definition in runtime
+- **Instantiate controlloop** - Instantiate the controlloop towards participants
+- **Check controlloop state** - check the current state of controlloop
+- **Change State to PASSIVE** - change the state of the controlloop to PASSIVE
+- **Check controlloop state** - check the current state of controlloop
+- **Change State to UNINITIALISED** - change the state of the controloop to UNINITIALISED
+- **Check controlloop state** - check the current state of controlloop
+- **Delete instantiated controlloop** - delete the instantiated controlloop from all participants
+- **Delete ControlLoop Definition** - delete the controlloop definition on runtime
+
+The following steps can be used to configure the parameters of test plan.
+
+- **HTTP Authorization Manager** - used to store user/password authentication details.
+- **HTTP Header Manager** - used to store headers which will be used for making HTTP requests.
+- **User Defined Variables** -  used to store following user defined parameters.

+===========   ===================================================================
+ **Name**      **Description**
+===========   ===================================================================
+ RUNTIME_HOST IP Address or host name of controlloop runtime component
+ RUNTIME_PORT Port number of controlloop runtime components for making REST API calls
+ POLICY_PARTICIPANT_HOST IP Address or host name of policy participant
+ POLICY_PARTICIPANT_HOST_PORT Port number of policy participant
+===========   ===================================================================
+
+The test was run in the background via "nohup", to prevent it from being interrupted:
+
+.. code-block:: bash
+
+    nohup ./jMeter/apache-jmeter-5.2.1/bin/jmeter -n -t stability.jmx -l testresults.jtl
+
+Test Results
+------------
+
+**Summary**
+
+Stability test plan was triggered for 72 hours.
+
+.. Note::
+
+              .. container:: paragraph
+
+                  The assertions of state changes are not completely taken care of, as the stability is ran with controlloop componenets
+                  alone, and not including complete policy framework deployment, which makes it difficult for actual state changes from
+                  PASSIVE to RUNNING etc to happen.

+**Memory and CPU usage**
+
+The memory and CPU usage can be monitored by running "docker stats" command. A snapshot is taken before and after test execution to monitor the changes in resource utilization.

+Performance Test of Controlloop components
+++++++++++++++++++++++++++++++++++++++++++
+
+Introduction
+------------
+
+Performance test of Controlloop components has the goal of testing the min/avg/max processing time and rest call throughput for all the requests with multiple requests at the same time.
+
+Setup Details
+-------------
+
+The performance test is performed on a similar setup as Stability test. The JMeter VM will be sending a large number of REST requests to the runtime component and collecting the statistics.
+
+
+Test Plan
+---------
+
+Performance test plan is the same as the stability test plan above except for the few differences listed below.
+
+- Increase the number of threads up to 5 (simulating 5 users' behaviours at the same time).
+- Reduce the test time to 2 hours.
+
+Run Test
+--------
+
+Running/Triggering the performance test will be the same as the stability test. That is, launch JMeter pointing to corresponding *.jmx* test plan. The *RUNTIME_HOST*, *RUNTIME_PORT*, *POLICY_PARTICIPANT_HOST*, *POLICY_PARTICIPANT_HOST_PORT* are already set up in *.jmx*
+
+.. code-block:: bash
+
+    nohup ./jMeter/apache-jmeter-5.2.1/bin/jmeter -n -t performance.jmx -l testresults.jtl
+
+Once the test execution is completed, execute the below script to get the statistics:
+
+.. code-block:: bash
+
+    $ cd ./clamp/testsuites/performance/src/main/resources/testplans
+    $ ./results.sh resultTree.log
+
+Test Results
+------------
+
+Test results are shown as below.
