prototype.js Ajax is slow

So I was doing some experimenting with prototype and ajax and discovered something interesting. When I use the first ajax call the response from the server take 53ms. When I use the second on using the prototype functions the request from the server is over 200ms. My question is why, and can it be fixed?

<p><a href="#" onclick="serverSideAlert();">Call server-side function</a></p> <p id="responseTxt"></p> <script type="text/javascript">   function serverSideAlert() {     var request = new XMLHttpRequest();     request.open('get', '/jstest/server_response', false);     request.send(null);     document.getElementById('responseTxt').innerHTML = request.responseText;   } </script>

<script src="/javascripts/prototype.js" type="text/javascript"> </script>

<p><a href="#" onclick="updateElement()">Update element </a></p> <p id="response"></p> <script type="text/javascript">   function updateElement() {     new Ajax.Request('/jstest/server_response', { onSuccess: function (request) {       $('response').update(request.responseText);     }})   } </script>

Thanks

You might find that the guys on the prototype-scriptaculous list are
more clued up on this.
