Reindexing process for consortium environment takes:
- 3 hours for 3 tenants in parallel (1.7M instances);
- 2 hours for central tenant reindexing (1.2M instances);
- 1 hour for secondary tenant reindexing (353K instances);
- 20 minutes for secondary tenant reindexing (202K instances).
Duration depends not only on instance number, but also it's its type (source). Data details can be found here: Datastructure
High CPU utilization is observed on nginx-okapi module - up to 413% during 3 tenants test.
CPU utilization for mod-inventory-storage reached 102% during test on central tenant. mod-search CPU utilization was about 13-27% during all the tests.
