Beside optimizing your db, you should reduce the count of http requests by using techniques like css sprites, or replace simple graphics by using css instead. check wether you can merge javascript files and compress them. check your headers for expiration timesout to cache files on client side.
at this url discount-deals you have 147 request for just one page! maybe the server can not handle these amount of connections.
good luck
