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."

DF BSD is a fork of FreeBSD 4.8, and a lot of work has been done in FreeBSD to remove the GKL(? Giant Kernel Lock), which I AFAIK was not ported to the DF kernel because Matt Dillion believed that this was the wrong approach. I wonder what he has to say in regards to recent benchmark improvements by FreeBSD?

I believe it would probably something along the lines that DragonflyBSD is really still in alpha (while it maybe usable for some people for daily use, it has implemented all its promised features yet of a transparent cluster). And that as long as the focus is on completing the core feature set, performance improvements are not being worked on beyond an as-needed basis.

Though I wonder: with these performance issues how will DF deal when it comes to work on them when the clustering is complete? Or perhaps it doesn't matter? Maybe the future of DF is in its niche of clustering where perhaps it will be unchallengeable, and then be adequate at the rest?

After all, OpenBSD isn't used for super-computing but has managed to find itself a nice niche in security conscious jobs.
