Overall check in time is 781 ms for a typical use case of 8 users, 1127.57 ms for 20 users
- Slow APIs taking more than 100ms to run:
- POST checkin-by-barcode
- GET inventory/items
- mod-circulation-storage log warnings for missing indexes - 64K lines in 45 minutes run. Logging level could be reduced to WARNING or INFO, but at the cost of having less data to work with should there be a need to troubleshoot. Adding the missing indexes could improve performance while stop logging these warnings
- Some mod-circulation-storage's SQL queries took more than 20ms to run, see the Slow Queries section and Recommended Improvements for the JIRAs created to address these SQL queries.

CIRCSTORE-215 - Missing Indexes Warnings CLOSED - JVM profiling shows JSON de/serialization operations one of the slowest operations, totaling more CPU time than other calls. Since FOLIO modules retrieve and stores JSON objects, making sure that serializing and deserializing JSON efficient is essential, see Recommended Improvements

- In mod-circulation and okapi consider using a more efficient JSON package or calling use the existing jackson serialization calls in a different way to address the item: JVM profiling shows JSON de/serialization operations one of the slowest operations.
