title: Web service vs. class file - performance
body: <p>I am trying to figure out the best way to go about doing this:  I am working on a project and I'm putting all my data access layer code into .ASMX files to keep them separated from my presentation layer.  I am calling all my methods from the code behind and using the web services like class files.  I am following this practice based on one other developer's work.  Two opinions on this so far:  One says when the code-behind calls the method from the web service, it's a performance hit because it has to go do an HTTP request and the other says, no performance hit.  The ASMX files are within the same project on the same server.  Is there indeed a performance hit or not really?  I tend to think not.  </p>
  
  <p>Any help or opinion on this would be appreciated.</p>
