Sumit, I'm working on profiling middleware and tools for Swift debugging on performance issue. This tool is powerful to get understanding how is code running at the function level by collecting metrics in statistical way. I think you maybe try this tool and see if you can get RTT at proxy server side. Remember to get the RTT information via query on the function __call__ of ./swift/proxy/server.py. Here's the patch. https://review.openstack.org/#/c/53270/24
I'm also thinking of proposing another tool to trace the request process
path and tie the timing
information together in order to give you a full picture in hierarchical
way so that you can understand
how well each Swift server component behaves for a specific request.
Any feedback is welcomed.

Hi
I want to see the Round Trip Time for swift request in proxy log. I am able
to see RTT for failures and timeouts and no RTT for normal requests. Do I
need to set and config param.
Thanks
