> I'm actually considering building out a very large sample site with various engines to demonstrate just how fast it is. I'll try to find this post on Hacker News again and post if I ever get around to it.

That would be fantastic. Do you have any shortlist of engines you are going to test?

Also, I have a question about the two website you've built. Did you also write the copy (content) yourself or was it sourced from the client/a third-party?
