Speed up wordpress site loading

I wondering if there is any way to speed up my wordpress site more? It loads at 2.75 via pingdom.com/. It is not to bad tho. But I want to atleast increase the loading speed to homepage. The loading speed from page to page isnt that important because then they are already at my site. It there any way to make the style.php load before the content to increase the speed?
I give it a try, because you are really good at what you are doing!
