We've just pushed a couple of site speed optimizations. Your Home page should load much faster now - my account's home page load time has been cut in half.
We've also made some changes to how we manage images that should help site speed on every page. We are experiencing a temporary issue where our placeholder animal images are showing up on item pages for folks who have real profile images - this should be fixed shortly.
Finally, item pages should load a bit faster now as well.
