documentation: control and data flow clarification

[hirenp]

If I look at Quick start - Multi server mode example from readme
$ python transperf.zip -v -x -c sample_config root@host1 root@host2 root@host3

which node is sender vs which one is receiver our of host1, host2 and host3?
I assume sender nodes are the ones we are testing from transport protocol performance pov.

A little more clarity in documentation could help. :-)

The first host (host1) will be the receiver, the rest will be senders.

This is noted in the README in that same section:

Note that the first host provided as a command line argument is used as the receiver.
