What is it running? You should consider nginx for the static stuff if you are not already using it. It really is fast and low memory usage on a small server such as that.
Edit:
Looking at your source here are two suggestions:
The load time is getting hurt by the 75 requests for small images in the success area. You should consider an ajax approach that lazy loads those images and doesn't request a ton of images. If that is too much just pick 5-10 randomly and serve just those on each page load. No one is going to wait through the 75 success stories without clicking on the link.
Also, you should minify the javascript and css to cut down on requests and request size.
