    Phoronix: FreeBSD/PC-BSD 10.3 vs. Linux Benchmarks

    With FreeBSD 10.3 having been released followed by the desktop-oriented PC-BSD 10.3 release that's running rather nicely, I decided to run some open-source performance benchmarks atop PC-BSD 10.3 x64 compared to various Linux distributions.

    Something looks funky with the clear linux setup. "-march=westmere"? That's a six year old processor.

      That's currently part of their default CFLAGS/CXXFLAGS.

        Understood. Still, that's strange. Thanks for the clarification!

          I read these benchmarks as follows:

          * ZFS - fast
          * Clang 3.4 - slow

          As in - freebsd benefits from using ZFS, but suffers from using Clang 3.4 as a builder, rather than gcc, which (still) generates better quality code.

          Am I off?

            Very likely, yes. So potentially GNU/kFreeBSD on ZFS could have the best of both.

              Those things generally cause little improvement, unless you have specialized hand-written code that makes use of newer processor instructions. Such code may live in the libc though ... (e.g., memset implemented with AVX2).

                Indeed ... Or Ubuntu BSD, which is alive .

                  I'm very interested. Unfortunately, FBSD 10.03 still no support accelerated graphics for the Intel Haswell processors, but I understand it will be there in FBSD 11.0, so I'm waiting for that.

                    How about ZFS on Ubuntu, aren't they have native ZFS support on 16.04? How will that compare to the ZFS optimized BSD?
