Is this correct? I am not sure it works as my performance figures dont indicate any change so perhaps they are not being resized at all. Any suggestions regarding how to do this would be great.
Its a ping pong test which sends msgs of different sizes to all nodes
in the cluster and generates some high traffic.. varying the packet
sizes and testing would help check if the buffer size is really
affected. may be you ran a processor intensive task, and that might be
the reason why you didnt find much difference. Or may be check if in
the program that you run, the push bit(PSH) is enabled.. In that case
even if you make your buffer large, every packet would be sent off
immediately, and you cant see the effect..
