In case people are wondering what makes DBSD so interesting, DragonflyBSD is:<p>- focused only on x64 architecture<p>- has an extremely small but exceptionally talented team of developers (e.g. Matt Dillon from DICE and Amiga fame)<p>- has it&#x27;s own unique filesystem called Hammer (and work is being down on Hammer2 which is a complete rewrite)<p>- Network performance is particularly good with Dragonfly and even better than FreeBSD which is known as being the golf standard for network performance [1]<p>[1] <a href="https:&#x2F;&#x2F;leaf.dragonflybsd.org&#x2F;~sephe&#x2F;perf_cmp.pdf" rel="nofollow">https:&#x2F;&#x2F;leaf.dragonflybsd.org&#x2F;~sephe&#x2F;perf_cmp.pdf</a><p>Edit: formatting<p>Edit2: it should also be noted in the release notes, it refers to detailed NVME disk performance testing the Dragonfly team performed. These results are largely agnostic of what OS you run. Really interesting to see the Samsung NVME device come out on top and Intel in last. This is a good read even if you don&#x27;t run Dragonfly.<p><a href="http:&#x2F;&#x2F;apollo.backplane.com&#x2F;DFlyMisc&#x2F;nvme_randread.txt" rel="nofollow">http:&#x2F;&#x2F;apollo.backplane.com&#x2F;DFlyMisc&#x2F;nvme_randread.txt</a>

I appreciate that there is so much operating system innovation coming from the *BSD&#x27;s like the Hammer file systems in DragonFly and security concepts like the new pledge() system call from OpenBSD which informs the operating system that an executing program pledges to never use certain system calls. (i.e. if you say you&#x27;ll never do something, the operating system will have the privilege of killing your application should there be some kind of buffer overflow&#x2F;compromise.)

Anyone using DragonFly BSD in production? Or as a desktop system? What is your experience? I love the BSDs, but never used DragonFly.

Been looking for Skylake GPU support for BSD. Does it support Skylake OpenCL?<p>How compatible is this with FreeBSD? Can I test it alongside a FreeBSD distribution with minimal changes? Does it use the same Ports&#x2F;Packages system? Do I need to recompile&#x2F;reinstall all applications? Is there ZFS support?

Checking the release notes, it does include the recent fix mentioned at <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=13882171" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=13882171</a> .

Awesome news, and props to the DBSD team for all the consistent hard work they put into it, usually without much fanfare. I&#x27;m a pretty hardcore GNU&#x2F;GPL guy, but I have said before if I were starting an ISP I would probably be doing it with DBSD. The networking stack alone is top-notch, and once HAMMER2 rolls out I honestly expect it to get the momentum to compete with ZFS and BTRFS. (not much traction now though, so as others have said, probably years down the road).

Strange that there is another dragonfly, a framework for newlisp.
