shoutbox

Hello guys,
I’m using “Nirvana” template on my site and I set up 3 shoutboxes that point to internal links, pages and categories.
When I click on the links I experience a lag of 3 or 4 secs before the page is displayed. These pages are accesible directly through the menu and when in that case the page display is immediate.
Do you have some suggests?

Thanks
Sergio
