DragonFlyBSD 5.4 & FreeBSD 12.0 Performance Benchmarks, Comparison Against Linux

Coincidentally the DragonFlyBSD 5.4 release and FreeBSD 12.0 lined up to be within a few days of each other, so for an interesting round of benchmarking here is a look at DragonFlyBSD 5.4 vs. 5.2.2 and FreeBSD 12.0 vs. 11.2 on the same hardware as well as comparing those BSD operating system benchmark results against Ubuntu 18.04.1 LTS, Clear Linux, and CentOS 7 for some Linux baseline figures.
