i am getting ajax response slow - php

Question

i am using the following code for pass and get data through ajax.
function passdata(id)
{
var top = document.getElementById("tname").value;
var first = document.getElementById("fname").value;
var font_top = document.getElementById("font_top").value;
var font_first = document.getElementById("font_first").value;
var image_top = document.getElementById("image_top").value;
var image_first = document.getElementById("image_first").value;
var poststr = "id=" + id +
"&top=" + top +
"&first=" + first +
"&font_top=" + font_top +
"&font_first=" + font_first +
"&image_top=" + image_top +
"&image_first=" + image_first +
"&actype=getevent";
var reqAddCart = new Subsys_JsHttpRequest_Js();
reqAddCart.onreadystatechange = function() {
if (reqAddCart.readyState == 4) {
if (reqAddCart.responseJS) {
document.location.href = reqAddCart.responseJS.ajax_redirect;
return;
}
else {
//alert(reqAddCart.responseText);
//showModal('abc');
document.getElementById('data_content').innerHTML = reqAddCart.responseText;
result = (reqAddCart.responseText||'');
var brokenresult=result.split("#");
}
}
}
var senddata = new Object();
var url = 'product.php?'+poststr;
//alert(url);
reqAddCart.caching = false;
reqAddCart.open( 'GET', url, true);
reqAddCart.send( senddata );
return false;
}
i am using the passdata function to pass the data in product page.this function works but i am getting response very slow.

Answer 1

The time taken for an AJAX request to complete is affected by network latency and connection speed on both the server and client, as well as execution time of the script on the server.
I would expect AJAX requests made locally when testing to return a lot faster as it removes the need for transmitting data over the internet.
