For those that don't know, FreeBSD boasts a Linux binary compatibility initiative. Five years ago I did some Linux gaming tests on FreeBSD within FreeBSD: A Faster Platform For Linux Gaming Than Linux?. I wanted to do some modern tests atop the latest FreeBSD/PC-BSD code and the latest NVIDIA driver.
So I decided to go for this month's PC-BSD 11.0-CURRENT release to get the bleeding-edge state of the FreeBSD performance and for best Linux binary compatibility. While PC-BSD ships with the support enabled by default and I did install all of the relevant CentOS-derived packages from Ports, I couldn't get any of my usual OpenGL Linux game / tech demo benchmarks (32-bit, since the 64-bit Linux binary support on FreeBSD is incomplete) running under 11.0-CURRENT. All my attempts were foiled by segmentation faults.
Five years ago I got the FreeBSD Linux binary compatibility support working real good as shown in those earlier results, but whatever the case, I couldn't get it working well on FreeBSD 11.0-CURRENT. After a few hours I had to throw in the towel and focus on other work. However, in not to spoil having a clean FreeBSD 11.0-CURRENT installation around, I did some quick benchmarks of this latest release.
PC-BSD 11.0-CURRENT with this month's image was using the 11.0-CURRENT kernel (obviously), GCC 4.8.5 and Clang 3.7 were setup as the compiler stack, and ZFS continues to be the default PC-BSD file-system. For putting the PC-BSD 11.0-CURRENT results into some perspective, I then installed Fedora 23 x86_64 on this same system: comprised of an Intel Core i7 5960X, 16GB of RAM, 120GB Samsung 850 EVO SSD, and NVIDIA GeForce GTX 750 Ti graphics.
If you want to see these PC-BSD 11.0-CURRENT vs. Fedora 23 Linux benchmarks from this Core i7 Haswell system, see this OpenBenchmarking.org result file for the few results to share today. As FreeBSD/PC-BSD 11.0 is nearing its official release, plenty more thorough benchmarks will obviously come.
