Running FreeBSD 12, TrueOS On AMD EPYC

With TrueOS and upstream FreeBSD supporting ZFS well, in some I/O tests it does continue to compete with or even outperform the tier-one Linux distributions.

The Assembly-written asmFish chess engine was faster on the Linux distributions over the FreeBSD 12 based TrueOS.

OpenSUSE Tumbleweed was the fastest at building out the LLVM compiler stack while TrueOS / FreeBSD were the slowest with the exception of Clear Linux running in between them. Clear's slower compile times are due to its aggressive CFLAGS/CXXFLAGS to enhance the performance of compiled binaries albeit at the expensive of slower compile times.

While the C-Ray multi-threaded ray-tracer was the fastest on Clear Linux, due to that Intel distribution's aggressive performance optimizations.

The Linux distributions were slightly faster than FreeBSD 12-CURRENT / TrueOS at LAME MP3 encoding, with Clear Linux again taking the lead.

The Linux distributions were faster than the FreeBSD-based operating systems with their Python performance measured by PyBench.

Clear Linux and Ubuntu 18.04 LTS were also a fair amount faster than PHP 7.1 as tested on FreeBSD 12-CURRENT.
