A large part of the reason PHP is so good at what it does is that scaling it up on a single, and then to multi-machine sites and from there to even millions of users is a well understood path. For APC, if you are running your own server and running a PHP site on there, if you're not already running APC or a similar caching system on there, you are just wasting CPU effort. There are a number of websites already out there that demonstrate the sort of caching and optimisations that can be performed on a LAMP stack, both within PHP code (but the various micro-optimisations of changing quotes and using one kind of array handling over another is only useful at the most extreme end of optimisations - and if you wonder if you need them - then you don't). I'll be writing on the topic of scaling on my blog soon as well, so it might be useful to keep an eye on the in the next few weeks as well. For now, http://google.com/search?q=scaling+PHP will give you a lot of food for thought. Topbit http://topbit.co.uk/
