Overview
This is a report for a series of Check-in-check-out test runs together with Bulk edits + Data Import in the Nolana release to see how these workflow interact with one another, especially because they all use mod-inventory.

MG- Morning Glory release
Front End:
- Item Check-in (folio_checkin-7.2.0)
- Item Check-out (folio_checkout-8.2.0)
High-Level Summary
- In general, response times for CI/CO are consistently good, even better than the CI/CO + DI test without bulk editing. We can observe a decrease in response time spikes number which can cause better results.
- Compared to baseline DI time increases for updates (baseline 24 min 5 s compared to test #4 and Test #3 about 30 min). Bulk edit time increases for tests with DI Create (about 10 min slower).
- No errors or issues were found during the run of 3 workflows (Check-in/Check-out 8 users + Data Import MARC BIB 50k.mrc + Bulk edit 10k Items or 10k Holdings records)
- Memory usage is stable for all modules, except for mod-source-record-manager, mod-source-record-storage, and mod-inventory increased (reason: modules were restarted manually before the tests. No memory leaks were found during modules memory leaks investigation PERF-358 - Getting issue details... STATUS ).
- For all services CPU usage did not exceed 130% for tests 1 and 2 and did not exceed 170% for tests 3 and 4.
- RDS CPU usage was high up to 94%

* - Before the Combined Bulk edit + Check-in-check-out + Data Import test, the Items Bulk edit scenario was changed to the latest requirements so the duration for bulk edits could differ.
Response times for CI/CO are consistently good, even better than the CI/CO + DI test without bulk editing. We can observe a decrease in response time spikes number which can cause better results.
Compared to baseline DI time increases for updates (baseline 24 min 5 s compared to test #4 and Test #3 about 30 min). Bulk edit time increases for tests with DI Create (about 10 min slower).
Memory Utilization
- Memory usage is stable for all modules, except for mod-source-record-manager, mod-source-record-storage, and mod-inventory increased (reason: modules were restarted manually before the tests. No memory leaks were found during modules memory leaks investigation PERF-358 - Getting issue details... STATUS ).
