This is a report for a series of Check-in-check-out test runs against the Honeysuckle release.

...
- 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.
...
- Subsequent investigations (
ANDJira Legacy server System JiraJIRA serverId 01505d01-b853-3c2e-90f1-ee9b165564fc key PERF-140
) 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.Jira Legacy server System JiraJIRA serverId 01505d01-b853-3c2e-90f1-ee9b165564fc key CIRC-1014
