If I understand correctly,
# On the main thread, this  application first check the flow insertion
performance
# and then start the worker thread for packet forwarding.
Why this application testing the packet forwarding?, We already have
testpmd for that.

IMO, This application needs to focus only on
- Insertion performance
- Deletion performance
- IMO, it is better to add a framework for the profile where the first
version of this application can
define common a set of ITEMS and set of ACTION and later others can extend it.
And the framework can run over all the profiles and spit out the
insertion and deletion
performance.
