DragonFlyBSD 6.0 atop its default HAMMER2 file-system tended to perform much more poorly than the rest for the PostgreSQL database server. FreeBSD 13.0 meanwhile was on ZFS.

From this Tyan 1U server a larger comparison of different Linux distributions will be coming shortly for showing a wider range of 2021 Linux distributions in their out-of-the-box performance state on AMD EPYC 7003 series hardware.

Those wishing to see even more of these reference benchmarks between FreeBSD 13.0 and DragonFlyBSD 6.0, see this result file. Both FreeBSD 13.0 and DragonFlyBSD 6.0 were happily running well on this Tyan GC68-B8036-LE server (S8036GM2NE motherboard) unlike some platforms that don't end up running well out-of-the-box on the BSDs. As to the out-of-the-box performance it largely depends upon the specific workloads of interest to you and if making any modifications to the default OS stack or other tunables but generally at least are performing in the same vicinity as Linux. BSD performance on newer hardware has at least matured in recent years with more comparable performance.
