Depending on your build pattern you can likely speed up rebuilds by using ccache. If that doesn't help get one or two (or more as needed) cheap dual core systems and use icecream (http://en.opensuse.org/Icecream) to do a cluster build and build with -jN (N=2*available cores/threads or so) To combine icecream and ccache in the same build you can use ftp://ftp.firstfloor.org/pub/ak/smallsrc/icecache.c For parallel builds modular builds are faster than static builds because otherwise the linker becomes a bottleneck. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
