I think you're better off keeping the channel open as well, and using it 
(just one channel) for all your requests, since you're sending only 
basic.publish (which is an async method). This way you can avoid the 
delay of sending channel.open and then waiting for channel.open_ok for 
every request.
Nagle is turned off in the Erlang client so the methods are sent promptly.
Also, I suggest you use amqp_channel:cast/3 rather than 
amqp_channel:call/3. The cast function returns a bit quicker than the 
call function (lets your process continue quicker).
