How can I speed up my server?

I have a Java client on a PC and a C++ server on a unix machine. The client calls the method with a structure, the values in the structure are modified and returned.

When I call the method once it takes appx. 1400ms
This is pretty slow compared with my XML-RPC version of the same test (it takes appx. 60ms)

The CORBA version does very well if I loop the test. If I call it 10 times it still takes appx. 1400ms, whereas the XML-RPC version gets slower, and slower.

However, I am only going to call it once in reality so would like to know if there's a way to speed it up?


My client call:
mySecuData = testImpl.test(userName, passWord, firstName, lastName, loginsLeft, lockedOut, comments);


My server:
CORBA::ORB_var orb = CORBA::ORB_init(argc, argv);
CORBA::Object_var obj = orb->resolve_initial_references("RootPOA");
PortableServer:OA_var rootPOA = PortableServer:OA::_narrow(obj);

CORBA:olicyList policyList;
policyList.length(1);
policyList[(CORBA::ULong)0] = rootPOA->create_lifespan_policy(PortableServer:ERSISTENT);
PortableServer:OAManager_var poaManager = rootPOA->the_POAManager();

PortableServer:OA_var testPOA = rootPOA->create_POA("test_poa", poaManager, policyList);
test_Impl testManagerServant("testinterfaceServant");

PortableServer::ObjectId_var managerId =
PortableServer::string_tbjectId("testinterface");

testPOA->activate_object_with_id(managerId, &testManagerServant);

poaManager->activate();

CORBA::Object_var testRef = testPOA->servant_to_reference(&testManagerServant);
cout << testRef << " is ready" << endl;
