Jquery inefficient code?

Question

Can someone please point out the inefficiency in this code? I get high CPU usage when running this code on my html website http://dev1.envisionwebdesign.co/johnreid/campaign.html. Also the animation isn't smooth. I have placed this script in the of my page. Is that also a reason why?

     <script>

    $(document).ready(function() {
        $("#copy2").animate({'position':'absolute','top':'-390px',opacity:1},1);
    $(".media-nav2").animate({'position':'absolute','top':'380px',opacity:1},1);

    $("#copy3").animate({'position':'absolute','top':'-390px',opacity:1},1);
    $(".media-nav3").animate({'position':'absolute','top':'400px',opacity:1},1);

    $("#copy4").animate({'position':'absolute','top':'-380px',opacity:1},1);
    $(".media-nav4").animate({'position':'absolute','top':'400px',opacity:1},1);

    $("#copy5").animate({'position':'absolute','top':'-390px',opacity:1},1);
    $(".media-nav5").animate({'position':'absolute','top':'400px',opacity:1},1);

    $("#copy6").animate({'position':'absolute','top':'-390px',opacity:1},1);
    $(".media-nav6").animate({'position':'absolute','top':'400px',opacity:1},1);

    $("#copy7").animate({'position':'absolute','top':'10px',opacity:1},1);
    $(".media-nav7").animate({'position':'absolute','margin-top':'450px',opacity:1},1);

    $("#copy8").animate({'position':'absolute','top':'10px',opacity:1},1);
    $(".media-nav8").animate({'position':'absolute','margin-top':'450px',opacity:1},1);

Answer 1

Thanks for your input guys. This worked for me. If there's anyway to improve this code, let me know.

 $(document).ready(function () {

        setInterval(function () {
            $('[id^="copy"]').each(function () {
                currentCopyID = $(this).attr('id');
                currentID = currentCopyID.substring(4, currentCopyID.length);

                if (!$(this).visible(true)) {
                    $(this).transition({ 'position': 'absolute', 'top': '-380px', opacity: 1 }, 1);
                    $(".media-nav" + currentID).transition({ 'position': 'absolute', 'top': '380px', opacity: 1 }, 1);
                }
                else {
                    $(this).filter(":onScreen").transition({ 'position': 'absolute', 'top': '0px', opacity: 1 }, 1700);
                    $(".media-nav" + currentID).filter(":onScreen").transition({ 'position': 'absolute', 'top': '250px', opacity: 1 }, 1700);
                }
            });
        }, 1150);

    });

}, 1);  // repeat every second

The code above repeats every millisecond.

}, 1000);  // repeat every second

The code above repeats every second, not millisecond.

Also, there are quite a few animation effects happening, which may play into it as well.
