      Description

      This Jira refers to the MODSOURMAN-454

      Module versions: mod-source-record-manager-3.1.0-SNAPSHOT.388 , mod-inventory-16.4.0-SNAPSHOT.358 .

      In my test I am using vb.cpus=12 and vb.memory=18000. No swapping happening.

      The system at boot deploys all modules.. This takes a couple of minutes. After this point, no user is logged on. However, the CPU load is 2 (200%) in total for the system. What is measured here is "TIME" .. Ie the total CPU usage user+system for a process.

      After 10 minutes, the system is surely turned to "idle" state and the top 4 contenders are: mod-source-record-manager 3:44 (3 minutes 44 seconds), mod-inventory 3:39, kafka 2:07, mod-pubsub-server 0:57. .. further down is list is Okapi 0:17.

      After one hour the stats are as follows: mod-source-record-manager 24:22, mod-inventory 24:01, Kafka 11:41, docker-proxy 5:50, mod-pubsub-server 3:25. Down the list is okapi with 0:37.
