AxisClient performance issue

[Felix Dierich <f....@planungsgemeinschaft.de>]

Hello Axis users!

I have developed a rather large project with Apache Axis and liked Axis
very much so far (with the occasional problem of missing documentation).

I have a performance problem with my client applications though: The
first call to the web service takes almost two seconds on rather fast
machines. The following calls take 100-200 ms which is perfectly OK, but
the clients mostly only make one call and take too long for that.

I have done a little profiling and tracked down the time consumption to
the constructor of org.apache.axis.client.AxisClient, which takes over a
second (with different VMs).

The relevant portion of my code is:

[...]
->  Service service = new Service(); // this takes very long <-

     Call call = (Call)service.createCall();
     call.setTargetEndpointAddress(axisUrl);

     call.setUsername(httpAuthUsername);
     call.setPassword(httpAuthPassword);
[...]

I have searched a little on the web and in the newsgroups, but have not
found a solution.

Is there any way to speed up the AxisClient? Have you had similar
experiences?

Thanks for your help in advance

Best regards

- Felix

Hello,
 
Would caching the service object help? I am facing a similar issue. I am thinking of caching the "PortType" object so that the binding operation is done only once.
 
Any inputs from the Group on caching the port Type?
 
Regards
