We were changing the "Number of threads" property for different test cases (1,2,4,8,16). Each thread will execute the test plan in its entirety and completely independently of other test threads. Each thread simulates a real user requesting to the server under a test. Multiple threads are used to simulate concurrent connections to server application. JMeter tool is configured on separate local Windows machine: Intel core i7, 16GB RAM. Keep in mind that mod-inventory calls mod-inventory-storage to save an incoming Instance. In it's turn, the mod-inventory-storage does SQL insert query. And yes, multi-threading is bandaid in this case, and we created specific Jira tickets to receive a batch of Instances in one request (). If you would need more details about test plan, here is it
