Thanks for the linode VPS tutorial on how to install mercury, I'm pretty sure I'd be flailing about biting my toenails had I not found it. But before I go ahead and install and configure it, I can't seem to figure out whether mercury is what I'd be needing because most of my users will be authenticated users.
From what it sounds like, varnish+pressflow+awesomesauce=Mercury and that is best for boatloads of anonymous users. So my question is what kind of performance gain would I get if I install mercury running a site built for authenticated users?
