Overview

The test's target is to investigate the behaviour of the Check-In/Check-Out activities during fixed load tests. PERF-879 - Getting issue details... STATUS

Summary IN-PROGRESS

Check-In/Check-Out tests on Quesnelia release (Eureka) in QECP1 environment carried out with 8, 20, 30, 75 virtual users during 45 minutes and with 30 virtual users during longevity test (24 hours) to detect any trends in resource utilization

45 minute tests

Response times in tests with 8, 20, 30 virtual users delta was 200 ms. The lowest average response times were with 20 virtual users test: Check-In - 625 ms, average Check-Out - 1356 ms
The highest average response times showed 75 vUsers test: Check-In - 4 sec 610 ms, Check-Out - 12 sec 589 ms (whole test), Check-In - 622 ms, Check-Out - 1540 ms (before saturation point with 33 vUsers)

Longevity test

Longevity test was running 10 hours and began failing because of token expiration. Possible reason here is SSO Session Max limitation 10 hours (fs09000000/realm-settings/sessions).
- Average response times in 10 hours test for Check-In - 1003 ms, Check-Out - 2870 ms
- First 5 hours 30 minutes average response times Check-In - 770 ms, Check-Out - 1773 ms, the next 4 hours 30 minutes - Check-In - 1295 ms, Check-Out - 4280 ms

Comparison with previous Quesnelia release (qcp1 environment) results:

8, 20, 30 vUsers tests were stable. And 75 vUsers test revealed saturation point during ramp-up period with 33 vUsers. After this point response times increased significantly with the same throughput.
There's a significant performance degradation compared to previous results from tests in quesnelia release on qcp1 environment (non-eureka):
- 8 vUsers - Check-out - 96%, Check-in - 48%
- 20 vUsers - Check-out - 61%, Check-in - 33%
- 30 vUsers - Check-out - 89%, Check-in - 55%
- 75 vUsers - Check-out - 1111%, Check-in - 695% (during whole test)
- 75 vUsers - Check-out - %, Check-in - % (before saturation point was found)

Methodology/Approach

Run data preparation script before each CI/CO test
Update .jmx file script for Quesnelia release
Create artefact and upload to carrier-io
Use Jenkins job to change parameters and run tests
Test CI/CO with 8, 20, 30, 75 concurrent users for 45 minutes each.
Test CI/CO with 30 users for 24 hours to detect any trends in memory.
