"In May 2007 I ran some benchmarks of Dragonfly 1.8 to evaluate progress of its SMP implementation, which was the original focus of the project when it launched in 2003 and is still widely believed to be an area in which they had made concrete progress. This was part of a larger cross-OS multiprocessor performance evaluation comparing improvements in FreeBSD to Linux, NetBSD and other operating systems. The 2007 results showed essentially no performance increase from multiple processors on dragonfly 1.8, in contrast to the performance of FreeBSD 7.0 which scaled to 8 CPUs on the benchmark. Recently Dragonfly 1.12 was released, and the question was raised on the dragonfly-users mailing list of how well the OS performs after a further year of development. I performed several benchmarks to study this question."

I remember Matthew Dillon was pretty harsh and insulting with how the FreeBSD Project was trying to solve the BSD SMP problem. I don't know if in the future Dragonfly will scale better than FreeBSD however two things are now certain. 1) As witnessed by the very promising scalability results we are now seeing, the FreeBSD Project was right to push forward and play it safe. 2) As witnessed by the utter lack of progress of SMP scalability in DragonflyBSD, while the road the FreeBSD project took was hard, the road Matthew Dillon was proposing was no walk in the park. I really think he should own up and apologize to the project now.
