Understanding WebRequests

In my code (C#) I'm using a WebRequest:

var request = WebRequest.Create(url);

For some reason this line takes about 2-3 seconds to run. I've looked for a solution, but couldn't find any for the creation of the request. I've tried different urls (http and https, google, etc.) but nothing seems to help. Did anyone else experience such a behavior? Can anyone explain what exactly is going on during the creation of the request? Any alternatives?

BTW - I'm on a 64bit Win 7 (Bootcamp)

Edit - measured 3.126 seconds with Stopwatch for the following code (wireless):

var request = WebRequest.Create("http://www.google.com");

On the same network, only wired, it took 0.01 seconds.

Thanks everyone!

Some people have found that proxy detection can take a ridiculously long time. If you know there won't be a proxy, try setting the WebRequest's proxy property to null.

var request = WebRequest.Create("http://www.google.com");
request.Proxy = null;

Update

I don't have any other ideas, but here are some things you might try to narrow down the problem.

  1. Enable logging by putting the following code in your config file:

    <configuration>
  <system.diagnostics>
    <trace autoflush="true" />
    <switches>
      <add name="System.Net" value="Verbose"/>
    </switches>
  </system.diagnostics>
</configuration>

  2. Check out the source code for WebRequest.Create in ILSpy or a similar tool, and try doing the same things it does directly. For example, you can try creating a new HttpWebRequest(...) rather than calling WebRequest.Create and see if you get the same behavior.
