PERF-130 - Getting issue details... STATUS
Overview
The purpose of this test is to define system behavior under load with user-search-filter workflow.
During test we find that weak point of this workflow is resource usage, more specifically it's CPU usage on DataBase side.
Version
- mod-users:17.2.1
- okapi:4.2.2

Service CPU usage
Most used modules:
- Mod-Users - 14-15% (default usage 3%);
- Mod-OKAPI - 12-13% (default usage 4%).
Service RAM usage
There's no visible memory usage for any of modules.
DB CPU usage
as you may see from screenshots below, there's high CPU usage caused by (according to performance insights) slow query SELECT jsonb,id from <tenant>_mod_users_users
Database load by wait
Database load by SQL
According to RDS performance insights to wait is CPU and it's 3.63 seconds.

Services CPU usage:
Services memory usage:
As in previous sample memory usage are not visible for relevant modules (mod-users. and okapi-b);
DB CPU usage:
DB load bu waits:
DB load by sql:
According to RDS performance insights to wait is CPU and it's 5.25 seconds.
