The blog seems like it’s as fast as it can be. Without going to better hosting. The forums though the time to first bite is twice as long.
There are far to many images on the page, if you sprite all the png’s then you’ll save a second.
Fix the fact it loads THREE index pages and save another second.
I’ve just installed this new skin. I did download a sprite plugin for wordpress but it didn’t seem to actually sprite any of the images but maybe it was just the skin.
