why isn't there a kernel compile time test in the 8150 test in the first place ? this would not start if you would stick to a standard test setup and not use tests not included there for anything.
I went through both BD tests (original one and compiler comparison) and no kernel compile time graph. don't try to refer me to openbenchmarking.org. the site has a horrible layour for me (completely unintuitive and unclear) and there are very few people that will actualy look there if they don't find information in phoronix.com articles.
Only tests used in articles are those in the Phoronix Test Suite / OpenBenchmarking.org, which are all in a standardized configuration. The results are on OpenBenchmarking.org.
I think it's safe to say that Phoronix has sold out just like the other sites, as Michael has declined to be "open" and provide his kernel compiling parameters, but instead just invited us to stay tuned for his next article.
I compiled the kernel with
time make-kpkg --initrd --apend-to-version=-test kernel_image kernel_headers
On the following setup:
64GB Crucial SSD as boot drive, also where the kernel source was compiled
16GB of DDR3-1600
and compiled it in 4 minutes and 30 seconds. HOWEVER, the actual compilation took between 1.5 and 2 minutes with 90%+ CPU utilization across all cores the entire time, and the rest was those scripts that run before and after, where CPU and disk utilization are all well under 50% the entire time. This casts doubt on exactly how Michael is timing this benchmark, as I'm sure he can't be timing the entire make-kpkg command, which is what any logical person would consider a timed kernel compiling, and there's no way that the Intel CPU can somehow magically perform the non-CPU bound portion of the compile faster.
Of course, even if you compile the Linux kernel 10 times a day, the supposed, let's say: 10 extra minutes of waiting(assuming that we're comparing just the compilation part), is hardly going to inconvenience anybody, and I dare say that a $1000 16 core Opteron will do just as good and probably better than a $1000 Intel Xtreme edition CPU, not that anybody should be able to notice or care about it when the times are already so fast to begin with.

Huh? It's all open-source and there as part of the Phoronix Test Suite. Fetch the Phoronix Test Suite and run "phoronix-test-suite benchmark build-linux-kernel" and it will download, setup, and run the build test just like I do and then spit out your times.
I agree the learning curve for the openbenchmarking.org site is difficult. I gave up when I first tried to understand the site. However, I think I will pick it up on second review. I was able to find some of the results in question - Intel Core i7 3960X kernel comp. It did take me one search, then 4 clicks to find, which is very acceptable, since I still don't have a firm grasp on how to use the site. I haven't been able to get PTS working on my machine (gentoo amd64) but I'ma try again on that.
