Our blog is running extremely slow on the front and back end. We've contacted our hosting solution (media temple) and they claim that the issue is not with our server (which we upgraded once already to try and solve the issue.) We've since added a cache plug-in which has helped a bit but we still find the site is much slower than it should or we'd like.
Any suggestions on how to optimize site performance?
Any suggestions on third-party developers that can review and modify our code to improve site performance?
