FreeBSD 13.0 vs. DragonFlyBSD 6.0 vs. Linux On AMD EPYC 7003 Series "Milan"
OpenJDK Java performance was quite similar among the tested BSDs and Linux distributions with the exception of Ubuntu 21.04 running noticeably slower, even with still using OpenJDK 11 like on Ubuntu 20.04.2 LTS. FreeBSD 13.0 happened to have a narrow first place finish in this particular DaCapo benchmark.
With the exception of the ChaCha20Poly1305 test where FreeBSD 13.0 was the fastest, the BSDs generally were trailing the Linux distributions with the Botan crypto library benchmarks.
It comes down to the particular workload for how well FreeBSD and DragonFlyBSD were standing up against the CentOS and Ubuntu Linux distributions tested. But generally speaking DragonFlyBSD 6.0 was trailing in many of the cases while often times FreeBSD 13.0 tended to put up a greater fight.
