Getting Initial context

Question

Here is some debug output from a simple test I run against a WL6.1
Server. Notice the 35 secs. it takes to get Initial Context.
-- Initializing bean access.
-- Succeeded getting naming context.
-- Execution time: 35047 ms.
-- Succeeded looking up jndi name.
-- Execution time: 453 ms.
-- Succeeded casting Home interface.
-- Execution time: 94 ms.
Second time I run the test from the same machine I get this.
-- Initializing bean access.
-- Succeeded getting naming context.
-- Execution time: 1907 ms.
-- Succeeded looking up jndi name.
-- Execution time: 312 ms.
-- Succeeded casting Home interface.
-- Execution time: 31 ms.
The pattern is consistent. First attempt to get the Initial Context
from any of my client boxes will take about 30 secs more than any
consecutive attempts.
Here is the code for getting the Context:
long startTime = 0;
if (logging) {
     log("Initializing bean access.");
     startTime = System.currentTimeMillis();
try {
     //get naming context
     Context ctx = getInitialContext();
     if (logging) {
          long endTime = System.currentTimeMillis();
          log("Succeeded getting naming context.");
          log("Execution time: " + (endTime - startTime) + " ms.");
          startTime =endTime;
     //look up jndi name
     Object ref = ctx.lookup("DynamicPool");
     if (logging) {
          long endTime = System.currentTimeMillis();
          log("Succeeded looking up jndi name.");
          log("Execution time: " + (endTime - startTime) + " ms.");
          startTime =endTime;
     //cast to Home interface
     dynamicPoolHome = (DynamicPoolHome) PortableRemoteObject.narrow(ref,
DynamicPoolHome.class);
     if (logging) {
          long endTime = System.currentTimeMillis();
          log("Succeeded casting Home interface.");
          log("Execution time: " + (endTime - startTime) + " ms.");
catch(Exception e) {
     if (logging) {
          log("Failed initializing bean access.");
     e.printStackTrace();
Am I missing something here ?

My first guess would be a DNS problem.
Also, creating an InitialContext loads a fair amount of classes. If you're
loading them over the network, that could also account for the slow-down.
