Speed question - XmlHttpObject

Speed question - XmlHttpObject

Hi all

I am not sure if this is the corrcet place to ask but I always get helpful responses so i thought its worth a try!

I have a panel within my website which pulls out and displays customer records.  The customer table contains over 10,000 records.

I trigger the panel via a button, however the displaying of the panel and the customer records can sometimes take up to 15 seconds via a browser.

When I run the query direct on the database I get the results back within 2-3 seconds.

I am using the following JS to display the panel - could this be causing the delay:

  1. function displayPrimaryContacts() {
        var url            =    "/ajaxscripts/displayPrimaryContacts.php";
        var info        =    "";
        xmlHttp            =    GetXmlHttpObject(displayPrimaryContactsDone);
        xmlHttp.open("POST", url , true);

        xmlHttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        xmlHttp.setRequestHeader("Content-length", info.length);
        xmlHttp.setRequestHeader("Connection", "close");


    function displayPrimaryContactsDone() {
       var output = '';
       if(xmlHttp.readyState == 4) {
          if(xmlHttp.status == 200) {
             output = xmlHttp.responseText;
             showAjaxPopup("Primary Contact Details", output, 600, 300, 1);
