I’ve finally gotten around to moving this site (along with all my other random sites) onto a single server. It’s all now hosted at Media Temple, on a 512MB (dv). We’ll see how that goes. I’ve got a bunch of things to write up once the move is complete, but if you’re seeing this then it looks like we’re most of the way there.
There’s definitely some more tuning and tweaking to happen, but at least I have my memory usage below 100%
