Question
java.nio socket problem
I am using java.nio to write a non-blocking socket program which is running in windows 2003 standard edition. After accepting a connection, I will create a thread to handle some tasks and then dispatch the thread. During peak hours, nearly over 1500 connections connects to our program. I have always set the bind function backlog to 2000. But I found that many clients cannot connect to our server. The client got an error tcp link down or connection reset by peer. I am wondering if windows can accept so many connections and java can handle so many thread simultanously since I seldom find this problem in linux environment.
Firstly, I think that if the network has problem but if connections are less, the problem seems to be gone. I am wondering if the server is overloaded in peak hours
Any idea? thanks

I think you can stress-test your server by creating an increasing number of dummy clients that are trying to connect to the server at the same time. If the number reaches 1500-2000 without any of the client threads failing to connect to the server, then it's probably a network bandwidth issue.
