Overview

The target of the test is to investigate the capacity of the Check-In/Check-Out activities.

PERF-459 - Getting issue details... STATUS

Summary

  • Test results (Test #1 & Test #2) show approx. the same saturation point - ~134 vUsers
  • The start point of the Performance degradation zone (Test #1 & Test#2):
    • check-in: ~110 vUsers & ~98 vUsers
    • check-out: ~75 vUsers & ~77 vUsers

Recommendations

  • Up to ~75 vUsers could be used for benchmark testing if it's necessary and based on business non-functional requirements
  • Run fixed load tests for the confidence of the Check-In/Check-Out activities under the 'comfort' load

~134 vUsers peak - Capacity point (~683 op), throughput growth has been decreased and response issues appeared (5** status code of 'okapi' due to unavailability of related modules) (see Grafana snapshot Test #1 - Throughput)

Based on Investigation of variability of test results:

  • AVG/Median check-in: [400;500] ms
  • AVG/Median check-out: [700;800] ms

~110 vUsers check-in - potential start point of performance degradation zone, the response time has grown up, a significant amount of requests has a response time of more than 500 ms (see Grafana snapshot Test #1 - Response time heatmap (option 'Check-in'))

~75 vUsers check-out - potential start point of performance degradation zone, the response time has grown up, a significant amount of requests has a response time of more than 800 ms (see Grafana snapshot Test #1 - Response time heatmap (option 'Check-out'))

Test #2 http://carrier-io.int.folio.ebsco.com/grafana/d/elIt9zCnz/jmeter-performance-test-copy?orgId=1&from=1677824973753&to=1677834380143&var-percentile=95&var-test_type=baseline&var-test=circulation_checkInCheckOut_orchid&var-env=int&var-grouping=1m&var-low_limit=250&var-high_limit=750&var-db_name=jmeter&var-sampler_type=All&var-Request=Check-In%20Controller

~134 vUsers peak Capacity point (~680 op), throughput growth has been decreased and response issues appeared (5** status code of 'okapi' due to unavailability of related modules) (see Grafana snapshot Test #2 - Throughput)

Based on Investigation of variability of test results:

  • AVG/Median check-in: [400;500] ms
  • AVG/Median check-out: [700;800] ms

~98 vUsers check-in - potential start point of performance degradation zone, the response time has grown up, a significant amount of requests has a response time of more than 500 ms (see Grafana snapshot Test #2 - Response time heatmap (option 'Check-in'))

~62 vUsers check-out - potential start point of performance degradation zone, the response time has grown up, a significant amount of requests has a response time of more than 800 ms (see Grafana snapshot Test #2 - Response time heatmap (option 'Check-out'))

Methodology/Approach

  1. Executed check ins with up to 200 concurrent vUsers and the interval between vUsers is 1 min.  (On carrier-io use the artifact "circulation_checkInCheckOut_orchid.zip")
  2. Scripts used:
    1. DB Refresh - checkin-checkout-db-restore.sql 
    2. DB Update - circ-data-load_item-level-requests.sh
