How long does it take to build all 24,000 packages in the DragonFly ports collection? Apparently about 22 hours on a dual Xeon machine (with I think 36 cores) or 48-core Opteron. This is with synth. I used to measure pkgsrc builds in weeks.

Impressive. Those Opterons seem to still have some life left in them!
