In this workflow we are checking the performance of the loading items on instance record (in holdings accordion) workflow running in the Fameflower release.  We will test it with 1, 5, 8, and 20 virtual users for 30 minutes.  A longevity test will also be executed to see if there were memory issues.

  3. Excess logging of 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.


  4. JVM profiling shows JSON de/serialization operations one of the slowest operations.

...

There aren't any WARNING statements of missing indexes in mod-inventory-storage, mod-source-record-storage modules.

The following WARNING statements of missing indexes were generated during a test run and logged by mod-circulation-storage:

...

Slowest queries which took the most of execution time were initiated by the mod_source_record_storage, mod-inventory-storage and mod_circulation_storage services presented in the following table:

  • In mod-inventory-storage 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.
