[zeromq-dev] message deliver time, PAIR, REQ-REP

[Maciej Wewior]

Hi all

I'm thinking about using zmq as the basic communication mechanism for an 
LTE protocol stack implementation.
First I wanted to measure average time messages of various size need to 
be transmitted between 2 nodes (threads or processes).
I tested 2 simple cases:
- 2 threads, 1 thread creates REQ inproc zmq socket the other creates 
REP one
- 2 threads, both threads create 2 PAIR zmq sockets, one for sending the 
other for receiving
I ran request-response sequences in the loop and measured the time 
needed to deliver the messages and the results were more or less the 
same for both cases.

My question is: is it what I shall expect in general? Is there any 
difference (when it comes to performance) between 2 threads 
communicating through PAIR or REQ-REP sockets?

Thanks
Maciej

p.s.
I'm just starting with ZMQ so I might do something wrong or I might have 
some weird view on the whole zmq stuff :)
