Hi,
Just to confirm what you are doing.
Machine 1 ( Axis SOAP client ) ---------> TCP/IP HTTP SOAP
-------------> Machine 2 ( SOAP Server )
Your example endpont address uses localhost
h ttp://localhost:8080/webservices/EscalierBeton.jws
<http://localhost:8080/webservices/EscalierBeton.jws>
I assume the cross machine test is:
h ttp://machine2:8080/webservices/EscalierBeton.jws
<http://machine2:8080/webservices/EscalierBeton.jws>
1. You could have a slow DNS lookup to resolve the domain name to IP address
If you are using Windows on Machine 1 you could add the domain name to the
hosts file for a test
Example: C:\WINNT\system32\drivers\etc\hosts
2. You could write a simple Java program that creates a Socket connect to
the Machine 2 and POSTs a prepared SOAP message. ( This is eliminate the
Axis client )
Socket socket = new Socket ( machine2:8080 )
OutputStream o = socket.getOutputStream
o.write ( HTTP protocol )
o.write ( SOAP content )
InputStream input = socket.getInputStream
read input
socket.close ()

Subject: WS Performance
Hi all,
I am using Axis to develop Web services, but until right now I was using
all WS locally. It took about 22milleseconds to execute. Very fast. However
I put them in a LAN, within two machines, and the same Web service took
about 4000 miliseconds to execute. I was astonished! What am I doing wrong?
I put in annexe my Test class in java so you can see what I am actually
doing to run all of them. All four Web services has only one method that
returns OK as a String when it is executed, nothing more than this.
Thus I would like to know what shall I do to make my WS more faster. I am
using axis 1.3.
Thank you so much,
Daniela
