The JMeter script used in the stability run injected +back to back traffic with 5 parallel threads with no pauses between requests. Since the JMeter threads operate +in synchronous mode (waiting for a request's response before sending the next request), JMeter injection rates autoregulate +because of the backpressure imposed by the response times. Even though the response times are high, the +"Response over Time" graph above indicates that they remain constant at large, throughout the duration of the test. +This together with the absence of notorious spikes in the kubernetes node CPU utilization suggests that the API +component is not strained. A more enlightning set of tests, would plot jmeter threads (increasing load) +against response times. These tests have not been performed in this release. -The performance test is performed on OOM-based deployment of ONAP Policy framework components in Intel Wind River Lab environment. -In addition, we use another VM with JMeter installed to generate the transactions. -The JMeter VM will be sending large number of REST requests to the policy-api component and collecting the statistics. -Policy-api component already knows how to communicate with MariaDB component if OOM-based deployment is working correctly. - -Test Plan ---------- - -Performance test plan is the same as stability test plan above. -Only differences are, in performance test, we increase the number of threads up to 20 (simulating 20 users' behaviors at the same time) whereas reducing the test time down to 1 hour. - -Run Test --------- - -Running/Triggering performance test will be the same as stability test. That is, launch JMeter pointing to corresponding *.jmx* test plan. The *API_HOST* and *API_PORT* are already set up in *.jmx*. - -Test Results ------------- -Test results are shown as below. Overall, the test was running smoothly and successfully. We do see some minor failed transactions, especially in POST calls which intend to write into DB simultaneously in a multi-threaded fashion . All GET calls (reading from DB) were succeeded. - -.. image:: images/summary-1.png -.. image:: images/summary-2.png -.. image:: images/summary-3.png -.. image:: images/result-1.png -.. image:: images/result-2.png -.. image:: images/result-3.png -.. image:: images/result-4.png -.. image:: images/result-5.png -.. image:: images/result-6.png diff --git a/docs/development/devtools/images/api-response-time-distribution.png b/docs/development/devtools/images/api-response-time-distribution.png Binary files differnew file mode 100644 index 00000000..e57ff627 --- /dev/null +++ b/docs/development/devtools/images/api-response-time-distribution.png diff --git a/docs/development/devtools/images/api-response-time-overtime.png b/docs/development/devtools/images/api-response-time-overtime.png Binary files differnew file mode 100644 index 00000000..c80a6a64 --- /dev/null +++ b/docs/development/devtools/images/api-response-time-overtime.png diff --git a/docs/development/devtools/images/result-1.png b/docs/development/devtools/images/result-1.png Binary files differdeleted file mode 100644 index 4715cd7a..00000000 --- a/docs/development/devtools/images/result-1.png +++ /dev/null diff --git a/docs/development/devtools/images/result-2.png b/docs/development/devtools/images/result-2.png Binary files differdeleted file mode 100644 index cd01147d..00000000 --- a/docs/development/devtools/images/result-2.png +++ /dev/null diff --git a/docs/development/devtools/images/result-3.png b/docs/development/devtools/images/result-3.png Binary files differdeleted file mode 100644 index 01e27a30..00000000 --- a/docs/development/devtools/images/result-3.png +++ /dev/null diff --git a/docs/development/devtools/images/result-4.png b/docs/development/devtools/images/result-4.png Binary files differdeleted file mode 100644 index 3fc2f36b..00000000 --- a/docs/development/devtools/images/result-4.png +++ /dev/null diff --git a/docs/development/devtools/images/result-5.png b/docs/development/devtools/images/result-5.png Binary files differdeleted file mode 100644 index 9b7140c6..00000000 --- a/docs/development/devtools/images/result-5.png +++ /dev/null diff --git a/docs/development/devtools/images/result-6.png b/docs/development/devtools/images/result-6.png Binary files differdeleted file mode 100644 index f07ea59e..00000000 --- a/docs/development/devtools/images/result-6.png +++ /dev/null diff --git a/docs/development/devtools/images/results-1.png b/docs/development/devtools/images/results-1.png Binary files differdeleted file mode 100644 index 35e1a965..00000000 --- a/docs/development/devtools/images/results-1.png +++ /dev/null diff --git a/docs/development/devtools/images/results-2.png b/docs/development/devtools/images/results-2.png Binary files differdeleted file mode 100644 index 82092025..00000000 --- a/docs/development/devtools/images/results-2.png +++ /dev/null diff --git a/docs/development/devtools/images/results-3.png b/docs/development/devtools/images/results-3.png Binary files differdeleted file mode 100644 index 69d430a2..00000000 --- a/docs/development/devtools/images/results-3.png +++ /dev/null diff --git a/docs/development/devtools/images/results-4.png b/docs/development/devtools/images/results-4.png Binary files differdeleted file mode 100644 index 47c0f5fa..00000000 --- a/docs/development/devtools/images/results-4.png +++ /dev/null diff --git a/docs/development/devtools/images/results-5.png b/docs/development/devtools/images/results-5.png Binary files differdeleted file mode 100644 index effd062b..00000000 --- a/docs/development/devtools/images/results-5.png +++ /dev/null diff --git a/docs/development/devtools/images/results-6.png b/docs/development/devtools/images/results-6.png Binary files differdeleted file mode 100644 index 1da1e366..00000000 --- a/docs/development/devtools/images/results-6.png +++ /dev/null diff --git a/docs/development/devtools/images/summary-1.png b/docs/development/devtools/images/summary-1.png Binary files differdeleted file mode 100644 index a9d3b61e..00000000 --- a/docs/development/devtools/images/summary-1.png +++ /dev/null diff --git a/docs/development/devtools/images/summary-2.png b/docs/development/devtools/images/summary-2.png Binary files differdeleted file mode 100644 index 2ca0c969..00000000 --- a/docs/development/devtools/images/summary-2.png +++ /dev/null diff --git a/docs/development/devtools/images/summary-3.png b/docs/development/devtools/images/summary-3.png Binary files differdeleted file mode 100644 index cd288d2b..00000000 --- a/docs/development/devtools/images/summary-3.png +++ /dev/null |
