My WordPress site (both admin pages and live) is very slow -- 2 seconds (if I'm lucky) to 5 or more (typically) between page loads. This predates the use of any addons, it was like this out of the box. This is with Launch hosting. Is this just what that level of service provides? I can't even stand to edit the site, let alone give it to end-users.
