Thanks for the extra information! Are you running the armel Debian image or the armhf Raspbian variant? Your Raspberry Pi results are very similar to the result I posted of Debian running on an old smartphone. If you are running the armel version, then that comparison makes sense, because the processor and clock speed are almost identical between the two devices. If you are running the armhf variant, then it makes less sense, because the Raspberry Pi's hardware floating unit should be much faster than the software floating point emulation used to obtain my result.

I definitely can shave seconds off with my Kernel customizations. Its like F1 lol Shaving seconds off is rock hard. I imagine it will depend on what else is running on the machine at the time. It might be better to drop to a root prompt and run it from there before the OS has change to load anything else. See if that makes much difference.

Running it in a VM wont be a true test but nice to see results anyway.


I will try on a Quad Core Xeon when I get home for you if that will help

We have covered a good set of results, I was thinking that someone working on some deep research military facility or from a super computer would post times over under 1sec lol! No such luck

That would be awesome! We are still missing MIPS, Alpha, and PowerPC results too, though. It seems like there isn't much variation within the same architecture, but there is much more variance between architectures. That might be partially due to the limited results we have for everything other than x86; I'm not quite sure.

Thanks for the extra information! Are you running the armel Debian image or the armhf Raspbian variant? Your Raspberry Pi results are very similar to the result I posted of Debian running on an old smartphone. If you are running the armel version, then that comparison makes sense, because the processor and clock speed are almost identical between the two devices. If you are running the armhf variant, then it makes less sense, because the Raspberry Pi's hardware floating unit should be much faster than the software floating point emulation used to obtain my result.

I'm using the Raspbian image. If I had another SD card I'd pop the armel image on it and post the result. Any other takers for that? :)

He doesn't have the 'Member' badge under his avatar either, I wonder if this has something to do with his group being set to 'Restricted (Profile)'?

So I went back to compiling the latest 3.8.8 Stable kernel last night and there is a significant performance decrease, With this test and overall system performance. I am getting >30Seconds with this test and the 3.8 Kernel compared with the 3.9RCx Kernel.

I got a warning once about a million years ago for posting a link to something so I think that's when my profile became restricted :-( I thought that got cleared though along with the warning...
