I also run a project with Apache+PHP on Debian, with SQLite and a standalone C program that it interacts with running on the same machine. The whole setup runs on a single, low-spec VPS, and it too easily withstood the HN front page a few months ago [0], with plenty of capacity to spare. I've found it amazing how much you can do these days with even a cheap VPS, and how many requests you can serve as long as you're disciplined about not going overboard with excessive dynamic content and knowing where your scalability pain points are (sometimes this isn't obvious until you really get a lot of traffic!).
