Overview

The test's target is to investigate the behavior of the Check-In/Check-Out activities during fixed load tests.

PERF-857 - Getting issue details... STATUS

Summary

Check-In/Check-Out tests on Quesnelia were carried out with 8, 20, 30, and 75 virtual users for 45 minutes and 30 virtual users for 24 hours to detect any trends in resource utilization (only 16 hours of results available).

45-minute tests

Response times in tests with 8, 20, and 30 virtual users didn't differ a lot but the lowest response times were with 20 virtual users. Average Check-In - 441 ms, average Check-Out - 893 ms
The highest response time results were with 75 virtual users. Average Check-In - 546 ms, Check-Out - 1176 ms
Reports: reports_test_results_8.zip, reports_test_results_20.zip, reports_test_results_30.zip, reports_test_results_75.zip

Longevity test

Average Check-In - 458 ms, Check-Out - 1258 ms (the results from the test 16 hours)
Longevity tests show the growth of memory usage of mod-agreements from 73 to 80%. No memory leaks were suspected during the longevity test for all other modules.
RDS CPU grew from 30% to 55% on average. So it has a growing trend during longevity test and spikes up to 96% every 30 min corresponding to the circulation job.
Grafana results

Resources

CPU utilization
- 45-minute and longevity tests consumed CPU in correspondence to the number of vUsers but some modules spiked during the 75 vUsers test - nginx-okapi - 423%, mod-users-b - 105%.

Memory consumption
- Longevity tests show the growth of memory usage of mod-agreements from 73 to 80%. No memory leaks were suspected during the longevity test for all other modules.

Average RDS CPU utilization
- 8 vUsers - 13%, 20 vUsers - 18%, 30 vUsers - 23%, 75 vUsers - 42% During longevity test CPU grew from 30% to 55% on average. So it has a growing trend during longevity test and spikes up to 96% every 30 min corresponding to the circulation job.

CPU (User) usage by broker
- Common CPU utilization by the broker during all tests was up to 12% with equal distribution between brokers

Common notes

Longevity test revealed Database CPU Utilization growing trend and CI and CO response time increasing.

Recommendations

Add more CPU to nginx-okapi to exclude module fluctuations

Methodology/Approach

Run data preparation script before each CI/CO test
Update .jmx file script for Quesnelia release
Test performed from load generator in the same region US East (N. Virginia)us-east-1
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 (only 16 hours results available).
