Performance

Considerations

1. Using mod-search for searching by naturalId instead of just doing a search in mod-source-record-storage has to decrease response time when the number of records in the system is more than 1M. (Using mod-search will be needed for possible future requirements to have automated linking not only by $0 but by some other data)
2. Disabling the linked instances counting for the mod-search authority request have to decrease the time of response.
3. Having only required fields in the mod-source-record-storage response will decrease the size of data that has to be transferred via HTTP. The necessity of this should be tested to define if such processing will decrease performance. 2 options there: get the record as jsonb from the marc_records table and retain only needed fields or construct a record field-by-field from the marc_indexers partitioned table.
4. Using mod-search and mod-source-record-storage bulk endpoints will decrease response time.

Testing

Performance testing has to be done on the environment with:

• > 1M authority records
• > 1M MARC-based instance records
• Prepared MARC bib records that have >50 fields that are applicable for linking and all these fields should have $0 values matched to existing in the system authorities..

Tests are needed for:

• 1 request/sec
• 10 requests/sec
• 100 requests/sec
• 1000 requests/sec

Based on testing results some performance improvements could be suggested if it will be required.
