FreeBSD 5 brought in a complex locking system to handle SMP, which was problematic for quite a while. DragonFly’s approach has been to shift to simplified lockless or token designs. The advantage of that simpler method is that now that all the parts are in place, it’s much easier to implement this SMP improvement, reliably.

These numbers are comparable to FreeBSD, and while they don’t exceed FreeBSD (and Linux posts the absolute best), it’s a vast improvement compared to what DragonFly 2.10 was doing, and all that improvement was accomplished in perhaps a week or two of work. That’s the ‘easier’ part coming in.
