Performance
The following performance tests can be found in the repo, https://gerrit.onap.org/r/admin/repos/integration, under "test/mocks/datafilecollector-testharness/auto-test". The "README.md" file explains how to run the tests.
Memory consumption
During maximum load, 3500 new files every poll for 24h, the memory consumption vary between 2 and 5,5 GB during file processing.
File handling capacity
Note! The simulators (MR, DR, and PNF) are run on the same hardware as the DFC during all the tests below.
