Overview

The target of the test is to investigate the impact of the Check-In activities with previously created item-level requests and to compare tested results with direct non-functional requirements (see Jira ticket).

PERF-349 - Getting issue details... STATUS

Summary

Test results don't show a substantial negative impact of Check-In activities with previously created item-level requests:
- The average response time of CI was approx. 340 ms and meet NFR (500 ms).
Expected high memory usage was detected for mod-circulation - 76%
All modules show expected CPU behaviour and typical workload - 28.4% in a peak

Methodology/Approach

Created hundreds of items with 10 item-level requests attached. These items were also checked out.
Executed check ins with 25 concurrent vUsers using these items for 30 minutes. (On carrier-io used the artifact "circulation_Check-IN_Nolana_ILR.zip")
Scripts used:
1. DB Refresh - checkin-checkout-db-restore.sql
2. DB Update - circ-data-load_item-level-requests.sh
