How to speed things up when reading WSDL?

[Ong Vua]

I'm creating a Service object using JAX-WS as below

URL wsdlUrl = MyCustomClass.class.getResource("./Opportunity.wsdl");
Opportunity_Service service = new Opportunity_Service(wsdlUrl, new QName("urn:crmondemand/ws/ecbs/opportunity/", "Opportunity"));

It took about 1 minute to create this Service object because the wsdl's size is about 6MB.

Is this normal or is there a way to speed things up?

Thanks
