HTTP Post requests using HttpClient take 2 seconds, why?

You might better hold off this for a bit, I just noticed I could be my fault after all. Working on this all afternoon, and then I find a flaw ten minutes after posting here, ts.
Hi,
I'am currently coding an android app that submits stuff in the background using HTTP Post and AsyncTask. I use the org.apache.http.client Package for this. I based my code on this example.
Basically, my code looks like this:
public void postData() {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://192.168.1.137:8880/form");
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("id", "12345"));
nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
Log.e(TAG,e.toString());
} catch (IOException e) {
Log.e(TAG,e.toString());
}
}
The problem is that the httpclient.execute(..) line takes around 1.5 to 3 seconds, and I do not understand why. Just requesting a page with HTTP Get takes around 80 ms or so, so the problem doesn't seem to be the network latency itself.
The problem doesn't seem to be on the server side either, I have also tried POSTing data to http://www.disney.com/ with similarly slow results. And Firebug shows 1 ms response time when POSTing data to my server locally.
This happens on the Emulator and with my Nexus One (both with Android 2.2).
If you want to look at the complete code, I've put it on GitHub.
It's just a dummy program to do HTTP Post in the background using AsyncTask on the push of a button. It's my first Android app, and my first java code for a long time. And incidentially, also my first question on Stackoverflow ;-)
Any ideas why httpclient.execute(httppost) takes so long?
