Running FreeBSD 12.0 With Intel Xeon Scalable Cascade Lake / Gigabyte S451-3R0 Server, Benchmarks Against Linux

FreeBSD 12.0 was running faster than CentOS 7 in the Numpy benchmark, likely due to the newer Python packages.

In some of the tests the default FreeBSD 12.0 performance is quite low due to its LLVM Clang compiler in the base packages still not enabling OpenMP support, but at least the GCC performance becomes competitive with the Linux distributions.

FreeBSD 12.0 was performing surprisingly well with the x264 and x265 video encode benchmarks but was outperformed still by Clear Linux.

FreeBSD 12.0 with GCC wasn't too far behind for the Himeno pressure solver benchmark.

Or in the case of the Stockfish chess benchmark, the OS doesn't play a pivotal role.

The Rustlang performance tended to be faster under Linux.
