Benchmarks "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."

Since it forked from FreeBSD around the time of 4.8 a more interesting comparison would be FreeBSD 4.8 and FreeBSD 4.9 so we could get a glimpse of the overhead given by the infrastructure for clustering added since then.

There were no significant performance changes made from 4.8 to 4.11. Even if there were, if dfly never picked them up then that's still a problem.
