[snip] Please don't top post, it ruins the flow.

Make buildworld is what takes the most time. Most middle of the road modern 
machines take something like around an hour and a half to build world. 
Kernel build takes around ten to fifteen minutes. On higher end hardware 
these times can be quite a bit less.

On really old enough hardware it can take much, much longer than this.

If you are not a kernel-hacking developer might I respectfully suggest 
beginning with RELEASE and NOT -CURRENT?
