We are experiencing severe performance issues with the Configuration Item (CI) reference lookup when clicking the magnifying glass from Incident and Change records.
Our CMDB contains approximately 2.3 million CIs, and simply opening the CI lookup takes a long time to load. This delay occurs before any manual filtering or paging is applied and is significantly impacting Incident and Change workflows where CI selection is frequent.
We are trying to understand the correct approach to improve CI reference lookup performance at this scale.
Question:
For large CMDBs, can modifying the OOB CI reference qualifier help reduce the load time when opening the CI lookup, or are there recommended approaches specifically for improving CI search performance at this scale?
