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, there are insignificant regressions in performance for Check-in and check-out during bulk editing. Bulk edit duration is shorter than without CI/CO.
Memory usage is stable for all modules, except for mod-data-export-worker increased from 57% to 60% (Stable CPU utilization was after reaching 98% in Morning Glory).
The relevant services overall seem to occupy CPU resources nominally. Only mod-authtoken seems to have the spikes but the processes did not crash. CPU usage of all modules did not exceed 41%, except for mod-users up to 75%.
RDS CPU utilization did not exceed 41%.

Response times are consistently good.

Memory Utilization

Memory usage is stable for all modules, except for mod-data-export-worker increased from 57% to 60% (98% in Morning Glory).

Modules CPUs Utilization

The relevant services overall seem to occupy CPU resources nominally. Only mod-authtoken seems to have the spikes but the processes did not crash. CPU usage of all modules did not exceed 41%, except for mod-users up to 75%.

Database and network

RDS CPU usage did not exceed 46%
