I've never used it in production, but I switched to it in the FreeBSD 6 era until FreeBSD 8 came out. I switched to it because FreeBSD 5 was a dog and couldn't stand it. I used it more recently on my x220 because they supported my Intel graphics card where as FreeBSD didn't yet. Even more recently I tried it for a client for their little-of-everything server. I didn't use it because they wanted some ZFS features (send/recv). Dragonfly got much better performance for things like NFS and their rather large MySQL databases, though.
