Question

I’m currently reloading (refreshing if you prefer that word more) my pages every 5 minutes but this is quite a long time for me. I don’t know how much a reload of a page with the code below affects the server and it’s just that I want to know; if I change the interval time from 5 minutes to 1 second, how much does this take on the server? Will it slow the server down? My website has over 5 visitors per half hour but it will be more after the update.

$(document).ready(function() {


    setInterval(function() {
        $('#loading-page').show().html('<img src="images/animation-loading.gif" alt="" title="Reloading the page">');

        $.ajax({
            url: 'get/statistics',
            type: 'GET',

            success: function(s) {
                $("#load-statistics").html(s);
            },


            error: function() {
                $('#loading-page').show().html('<img src="images/exclamation-red.png" alt="" title="Couldn't reload page. Trying again soon">');
            }
        });
    }, 300e3);


});

Thanks in advance.

You can test it yourself. Try this:

var start = new Date().getTime();

$.ajax({
    url: 'get/statistics',
    type: 'GET',

    success: function(s) {

        var end = new Date().getTime();
        console.log('milliseconds passed', end - start);

        $("#load-statistics").html(s);
    }

});​

Check the console for the processing time. You can then change the interval time based on the average of lets say 10-20 sample time you will get at the console.
