See the excellent handbook chapter on it : http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html Personally the first thing I do on any FreeBSD install is to compile a custom kernel, taking out all the things I don't need and adding in IPFW support and the like. It takes very little time on a reasonable computer (and certainly not a prohibitive amount of time even on very slow computers - I have done kernel recompiles on a 486 in reasonable amounts of time). Think of it this way - most systems in use with FreeBSD right now, I would imagine, have only one processor, so does it make sense to clutter the generic kernel with code that most systems won't use? With a source-provided OS, there's no need to do that.
