Following last week's DragonFlyBSD 4.6 benchmarks I carried out a fresh comparison of FreeBSD 10.3 vs. FreeBSD 11.0 (Beta 4 at the time) along with the DragonFlyBSD results and a few of the popular Linux distributions. Here are those numbers.
Tested for this comparison were DragonFlyBSD 4.4.3, DragonFlyBSD 4.6.0, FreeBSD 10.3, FreeBSD 11.0-BETA4, Ubuntu 16.04.1 LTS, Ubuntu 16.10 in its current development state, Intel Clear Linux, and CentOS Linux 7. The x86_64/amd64 version of each OS was tested on a clean install each time using the same system hardware and each OS left to its default settings/packages.
The system used for testing had an Intel Xeon E5-2687W v3 Haswell CPU (3.1GHz base, 3.5GHz turbo), MSI X99S SLI PLUS motherboard, 16GB of RAM, NVIDIA GeForce GTX 770, and PNY CS1211 120GB SATA 3.0 SSD.
All of the Linux and BSD operating systems were benchmarked in a fully-automated and reproducible manner using the open-source Phoronix Test Suite benchmarking software.
