How to improve the performance of web service

[Maya Pillai]

I am accessing a .NET web service from a java client. My problem is it is taking more time to load. Can anyone suggest a better method to improve the performance. Currently it is taking 6-7 seconds for loading 250 records.

import org.apache.axiom.om.OMAbstractFactory;
import org.apache.axiom.om.OMElement;
import org.apache.axiom.om.OMFactory;
import org.apache.axiom.om.OMNamespace;
import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.client.ServiceClient;
public class AAA {
        private static EndpointReference targetEPR = new EndpointReference(
                        "http://ip/Service.asmx");
        public static void main(String[] args) {
        	long a = System.currentTimeMillis();
                try {
                                 OMFactory fac = OMAbstractFactory.getOMFactory();
                                 OMNamespace ns = fac.createOMNamespace("http://tempuri.org", "ns1");
                    	System.out.println("3");
                        OMElement payload = fac.createOMElement("GetDetails", ns);
                               Options options = new Options();
                    	System.out.println("5");
                        ServiceClient client = new ServiceClient();
                         options.setTo(targetEPR);
                        options.setAction("http://tempuri.org/GetDetails");
                             client.setOptions(options); 
              OMElement result = client.sendReceive(payload);
                    	                    
                } catch (AxisFault axisFault) {
                        axisFault.printStackTrace();
                }
                long b = System.currentTimeMillis();
                System.out.println("TIME:"+(b-a));

        }
}
