our configuration: client and server are on different windows machines. we tried it with single or multiple clients. each client opens 10 connections and sends messages sized 40bytes.
In our results we get a send and receive rate of around 2000 messages per sec for sending 250,000 messages. while sending 500,000 messages we get similar results it seems that neither the CPU (70%) nor the network is the problem. but can not receive fast send rates nor a receive rates
