High-Level Summary

...

mod-search performance is good without any background load but degrades gradually under background Elastic Search reindexing of Inventory instances. The background load is on the second tenant.

Query	1 user - Baseline (avg)	1 user - Under the reindexing load (avg)	20 user - Baseline (avg)	20 user - Under the reindexing load (avg)
Regular	336 ms	448 ms	728 ms	0.850 ms
Wildcard	1.42 seconds	1.63 seconds	2.32 seconds	2.71 seconds (2 failed requests for /search/instances: title all *1randomword)

*Note that "Regular" queries are queries that don't have the wild card character ( * ).

Show total requests processed increases as we increase the number of users concurrently.

Longevity 24 hours test

Looking at CPU, Memory and Graphana dashboard, the longevity test for mod-search looks promising. mod-search is stable. Http request for wildcard prefix failed which is expected fs09000000GET /search/instances: title all *1randomword_GET_500

Also, not related to mod-search, there was an issue with the carrier io environment but other than the test looks good.
