Slow performance with javax.xml.ws.Endpoint.publish method

Question

I've published an endpoint on my computer with the javax.xml.ws.Endpoint.publish method. When I'm load testing my endpoint on the local machine, with the client side in another jvm, the endpoint reacts very fast (server side(endpoint) and the client side on the same computer). There's not performance problem there.
But when I try to run a load test with the server side endpoint on my local computer and the client side on another computer the endpoint reacts slow, very slow compared to the local scenario. Instead of 500 requests / second I get like 3 requests / second. Why?
When I look at the traffic between the client and the server running on different machines it's like 4,5 kB/sec on a 100Mbit connection. And almost no cpu activity (neither server or client).
When I've a web server, like Tomcat or Sun Java Application Server and deploy my endpoint there the traffics goes up to 400kB/sec. So then it works fine with good performance over the same network, same ip address, same port and everything.
Why is my endpoint so slow when I publish it with javax.xml.ws.Endpoint.publish instead of on a for example Tomcat. And why is the endpoint fast when I'm running client and server on the same machine?

Answer 1

the timeout is a client side thing, most likely. you need to set the http request timeout on the client.
