In case people are wondering what makes DBSD so interesting, DragonflyBSD is:

- focused only on x64 architecture

- has an extremely small but exceptionally talented team of developers (e.g. Matt Dillon from DICE and Amiga fame)

- has it's own unique filesystem called Hammer (and work is being down on Hammer2 which is a complete rewrite)

- Network performance is particularly good with Dragonfly and even better than FreeBSD which is known as being the golf standard for network performance [1]

Edit: formatting

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't run Dragonfly.

I know you probably meant "gold standard" but I was amused thinking about what a golf standard might mean ;)

I appreciate that there is so much operating system innovation coming from the *BSD'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'll never do something, the operating system will have the privilege of killing your application should there be some kind of buffer overflow/compromise.)

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

I run a little VPS on DragonFlyBSD that I use for misc hobby projects and personal file hosting. Mostly it runs Postgres. It's quite fast. I had redis running on there as a message queue for a distributed web crawler for a while. I benchmarked it against Arch Linux (which is what I was using on that server before DragonFly) and it was somewhat faster.

HAMMER is a really nice filesystem. It's not one of the fancy COW filesystems (HAMMER2 is, though), but it still has built-in versioning and snapshots and a host of other features. It's great for storing personal projects on.

It's also rock solid and easy to tinker with. I've recompiled my kernel several times with various configs and patches. It is probably the easiest production-ready OS to hack around with.

Also #dragonflybsd on efnet is super helpful.

I wanna know that too. Never heard of anyone using it in production.

The hammer FS might be its main improvement. I think it's, right now, an exercise in maintaining options.

Why do you assume he meant "gold standard"? Have you ever seen how fast a golf ball flies just after a strong hit?
