In addition to what others have suggested, the devel/ccache port can 
seriously reduce world and kernel compilation time by caching results. 
Stuff that hasn't changed comes out of cache rather than from a 
recompile.  A buildworld every few days usually takes only about a 
fourth of the time it would take without ccache.  Unfortunately, so far 
it only has this extreme an effect with gcc, not so much with clang.

I usually use 4G of cache space; haven't tested to see how much is 
actually needed.  Setting CCACHE_COMPRESS=yes fits more files in the 
cache.  In my tests, there was no speed penalty.
