Check-out: Honeysuckle is slower by 9%-28% than Goldenrod
Check-in: 4%-22% slower than Goldenrod
APIs turned slower in Honeysuckle: GET /automated-patron-blocks/{id} (150% slower) and GET /circulation/loans (60%). These are covered by MODPATBLK-70 and CIRC-1014, respectively
Okapi v4.3.3 seem to be using 2x-3x CPU cycles than in v1.3.2 (Goldenrod). Potential issue found with the logging methods OKAPI-964
mod-pubsub has a memory leak that would drag down performance under high loads (see section on longevity test): MODPUBSUB-136
Caching Okapi tokens in Okapi reduced mod-authtoken's CPU usage by over 90%
Database's memory usage improved dramatically from Goldenrod's - little memory consumptions observed.

...

) on GET /circulation/loans do not show degradations by the API itself. We hypothesize that other API calls that were executed during the test run may have dragged down the response time, particularly if it was trying to read and write to the same rows in the database at the same time.

Honeysuckle tests revealed the following missing indexes:

8 Hours Longevity test run for 20 Users

Service CPU Utilization:

Okapi-4.6.1 consumes less CPU gradually from 1st hour into 8th hour. However, at the same time, mod-pubsub consumes more CPU by gradually increasing from 50% to almost 160%

Image Added

Service Memory Utilization:

Memory usage for okapi-4.6.1 and other modules is relatively constant and stable throughout the run. mod-circulation memory consumption increases to 125% and then stabilizes.
