The performance test https://github.com/folio-org/folio-perf-test/blob/ad414b0/Folio-Test-Plans/mod-inventory-storage/instance-storage/instance-storageTestPlan.jmx#L290
running /instance-storage/instances?query=source=abc takes 360 seconds on average.
There is no index for the source field resulting in a full table scan.
Other fields like title have a full text index and are fast (?query=title=abc).
- If there a possibility in the front-end to run such a query? If not I suggest to change the performance test to query the title instead of the source field. And to close this issue as won't do.
- Otherwise: add fulltextext index for the source field
