Help! First Accessing to Service on remote machine is very slow!

Dear All

 

         When I use RPCServiceClient  access to call the Axis2 web services
on the local machine，it is very fast。

But when I use RPCServiceClient to call the Axis2 web services on the remote
machine,it's very slowly,especially on the first time I call the Axis2.

 

         When I call the Axis2 on the remote machine continuously,the result
is :

             1,wait0seconds，use 17516 milliseconds

             2,wait1seconds，use 15 milliseconds

             3,wait2seconds，use 16 milliseconds

             4,wait3seconds，use 16 milliseconds

             5,wait4seconds，use 15 milliseconds

             6,wait5seconds，use 16 milliseconds

             7,wait6seconds，use 15 milliseconds

             8,wait7seconds，use 16 milliseconds

             9,wait8seconds，use 16 milliseconds

             10,wait9seconds，use 16 milliseconds

             30,wait29seconds，use 15 milliseconds

             31,wait30seconds，use 16 milliseconds

             32,wait31seconds，use 15 milliseconds

             33,wait32seconds，use 17281 milliseconds

             34,wait33seconds，use 17282 milliseconds

             35,wait34seconds，use 17281 milliseconds

             36,wait35seconds，use 17406 milliseconds

 

         The source Code is:

 

         public static void  test() throws ServiceException{

  long time0,time1,time2,time3;

  try {

   time0 = System.currentTimeMillis();

   String method="getVersion";

   String ret = null;

   RPCServiceClient rpcClient = new RPCServiceClient();

   Options options = rpcClient.getOptions();

   EndpointReference targetEPR = new
EndpointReference("http://168.5.128.92:7201/axis2/services/Version");

   options.setTo(targetEPR);

   options.setTimeOutInMilliSeconds(120000);

   QName opPrint = new QName(NAMESPACE, method);

   Class[] returnType = { String.class };

   Object[] opAddEntryArgs = new Object[]{null};

   for(int i=0;i<100;i++){ 

    time1 = System.currentTimeMillis();

    Object[] retVal =
rpcClient.invokeBlocking(opPrint,opAddEntryArgs,returnType);

    time2 = System.currentTimeMillis();

    System.out.println((i+1)+",wait"+ i +"seconds，use "+ (time2-time1)+"
milliseconds");

    Thread.sleep(1000 * (i+1));

   }

   rpcClient.cleanup();

  } catch (Exception e) {

   throw new ServiceException(e);

  }

 }

 

 

 Thank you.
