i did setup this NodeJs TCP Server and tested it with a message flooder. Just to see how the performance of the server is.

While the message throughput is great if i run the server and the message flooder on the same computer (ubuntu), the throughput dramaticaly decreases if i start the server on computer1(ubuntu1) and the message flooder on computer2(also ubuntu). Both PC are on the same network. In fact, they are directly connected to each other.

I started searching the internet for reasons and i suppose i need to tune TCP on both Ubuntu-pcs but until now i haven't been successfull at all.

Has anyone experienced such problems, or could someone help me out?

Thanks

Here the flooding code:

var net=require('net')
var client = net.createConnection(5000, "10.0.0.2")

client.addListener("connect", function(){
    for(var i = 0; i < 1000; i++) {
        client.write("message ");
    }
})
