it's very inefficient. and it is (well, at least the way most people write it), EXTREMELY hard on a server.
you may be using those programs considerably, but how much traffic are you driving to it? what's your server specs, and are you running several on one server?
i've seen phpnuke crash a lot, but only on sites with heavy traffic.
simply put, there's nothing to replace it, so just know what you're getting into. if it's written poorly, it will perform poorly. i've seen comparable software packages written in php that do essentially the same thing, where one could be extremely efficient, and one could require a whole dually dedicated server just to run.
