I have noticed that when I load the homepage fresh (ie no cache) the area to the top left with the title and the various links takes a while to load.I presume this is due to the large number and size of the images in that area.
In order to alleviate that problem I have a small suggestion. It’s not much but I feel it may help speed load times just a tad. If you were to take the title graphic as an example, at time of writing it is a .gif weighing in at 3.42KB. Simply by converting that graphic to .png it goes down to 2.57KB.
That around a 25% saving just by changing formats.
Here’s the link to the converted .png http://img62.imageshack.us/img62/1839/kongtk3.png
It is also worth mentioning I used optipng to convert the file since that will offer some lossless compression too.
It could also be edited to remove the slight bit of red at the top which is redundant.
