You guys should just STFU and get back to coding under whichever license you prefer. Otherwise there will be less both BSD and GPL code - which means there would be more proprietary code.
Or you can continue trollwars, with hope someday to create trollcompiler so that each of your claims here actually work. Which will never happen. Because you will all be banned and your time wasted.
You sure about this? The Phoronix test data sheet states that the DragonFlyBSD 3.21, 3.03 tests where done with GCC 4.47, which as far as my memory goes certainly has openmp support, the test results do indicate that you are right though. I fully agree though that for a test lke this to be anything close to fair the same compiler toolchain/version needs to be used across all systems, as it stands it's pretty worthless.
Well to cut Ubuntu some slack, I imagine this is vanilla Ubuntu which is running dash and lots of other stuff together with compositing etc which can affect benchmarks.
Also I'd say that in many (most?) of these tests done here the kernel version does not have a big impact, compiler toolchain, filesystem used and the settings applied, number of applications/services running by default etc seem more likely to affect the outcome unless the benchmark targets an area which has had great improvements between kernel versions. Overall I think these tests just highlight the general sloppiness which have become synonymous with 'Phoronix benchmarking'.
GCC version alone is not enough, as it can be compiled without OpenMP. (libgomp needs separate porting to platforms)
Your nickname alone makes me wonder that you actually know the word "behaviour".
And while we're at fragmenting: How many Linux distributions with incompatible package formats are out? Hmm.
