why is animate so laggy in ie8 and below?
<p>hi I have used jQuery animate to animate the padding on my menu items. It is very simple code as follows:</p>

<pre><code>$('.menu li a').hover(function(){
    $(this).animate({
        paddingLeft:'18px',
        paddingRight:'18px'
    }, 350);
}, function(){
    $(this).animate({
        paddingLeft:'5px',
        paddingRight:'5px'
    }, 350);
});
</code></pre>

<p>But for some reason in IE8 and 7 it is really really laggy. Anyone got any ideas. A lot of the javascript is laggy for that matter but I don't know why. The website is
