Hello,

I am not sure I understand your test quite well. Basically you are 
connecting and deconnecting very quickly. Is that the case ?
If this is the case, what are you trying to benchmark ?
Most of the time mesuring the TCP/IP throughput implies trying to know 
how much data can be processed through a TCP socket, but usually a long 
running one.

My experience in Erlang, shows that it can handle very well simultaneous 
process, so you can have many processs and thus connexion 
simultaneously. I did not try to benchmark quick connect/reconnect. From 
experience, there might be some performance problem. It looks like a 
denial of service for the application.

Does it answer your questions ?
