Thanks for all the help Macmanx!
Thanks again Macmanx. I guess I’m not so much worried about how much memory I’m using as wondering how someone could manage to get it so low (I’ve seen a few sites around 5-6mb)? The lowest I’ve ever seen on my own installs is around 12mb per request; cutting that in half (with not just a base WP install but a few plugins loaded as well) must be some kind of magic!
Thanks Macmanx. How about if I’m not even using any plugins? WordPress seems to be using around 16mb of memory per request, but I’d like to get it even lower if that’s possible.
