the way i understand it is this... if your objects (images, css files, html files... etc) go over the packet size then they spill over into the next one, so they take longer to send.
but you can definitely fit more than one object into each packet. so it pays to get them as small as possible. 4 objects weighing 2KB each all fitting inside just one packet, is going to be quicker than 4 objects of 8 KB each in four packets.
