Performance tests

The current performance test of ACM-R is made by jmeter. The jmeter file is configured with a cycle where a composition in created and primed, and an instance is deployed, undeployed and deleted. The test is made again a Kubernetes environment defined in policy/docker.

We need to investigate the performance of ACM-R whit hundreds of compositions and instances deployed at same time and determine minimal/recommended requirements of memory and CPU.

Test using 100 compositions and instances

Test made with 5 user and 20 instances for each user. Components version: 7.1.1
