Back when Dragonfly 6 was released, phoronix found it quite performant in their benchmarks[0].
Kind of wish HAMMER2 development switched to Linux and got a big boost in visibility and exposure. I've been excited about it for ~15 years, but I've never gotten enough round-tuits to put it to any real use. I'd love to switch my rsync+ZFS snapshots backup servers over to HAMMER, but ZFS works great except for deduplication.
Can somebody explain the niche or role of Dragonfly BSD? I'm only vaguely familiar with BSDs. So far my impression is that OpenBSD is the secure one, FreeBSD is the fast one (for servers). What's DragonFly good at?
