Summary
- Load tests showed that single tenant ListApp refreshing duration is:
- 2.6 min for 1 user test;
- 3.1 min for 3 user test;
- 4.2 min for 5 user test;
- 6.5 min for 10 user test.
- Duration is below the maximum accepted value of 10 minutes.
- Load tests showed that ListApp refreshing duration increases 2-3 times when conducted with the same user number but on 1 tenant instead of 3 tenants. For example, during 3 users test duration increased from 1.5 min to 3.1 min, for 10 users - from 2.3 min to 6.5 min.
- During the 10 users test CPU utilization reached 89% for mod-fqm-manager and 101% for mod-lists. In comparison with multiple tenants testing, CPU utilization for mod-fqm-manager is about 2 times lower for single tenant test.
- Maximum DB CPU utilization reached 63% (writer instance) and 99% (reader instance) during 10 user test.
...
- In comparison with multiple tenants testing, RDS CPU utilization for writer instance is 20% lower for single tenant test.
- No memory leak is suspected for all the modules.
