I'm playing around with the EveryThing Engine myself and my box is on a very fast pipe. It too seems to be a little slow in bringing up the main page. I think the site is being slowed down due to database access. A lot of functions are stored in the database as well as all the information from each node. So it seems that the DB is doing double duty.
On a separate note, it seems that The Everything Development Company is having a problem. So I have a mirror of the pre-1.0 engine download here along with a few nodeballs I had on hand. My way of saying "Thank you" to the main developers of the engine.
