How do I make the javascript more fluid? it seems to lag when two things are happening at once
<p>I have created this website but noticed the javascript image slider seems to lag the menu pointer when a image transition is happening..</p>

<p>Anyone got any tips for optimization or ideas on how I could resolve this issue?</p>

<p>Thanks!</p>
