How much bogomips get the AOne in linux?

What's Bogomips?
I know what mips are, just never heard of bogomips.

it's just a test speed of the machine in Linux and it's printed before X-window system starts.
Used for compare systems independant of which CPU is used

I wonder how many BOINGmips that is? :-D

You should be able to get the bogomips by doing:

cat /proc/cpuinfo

It works on ia32, ia64 and sun4u so I imagine it would work with PPC ^_^

I get 1266 on my A1-G3@599Mhz.

Marginally more per Mhz than on my P3 laptop (1394 @701Mhz)

My AMD Duron @750Mhz does 1642 bogomips in SUSE linux

To answer my own question:

From whatis.com
"Bogomips is a measurement provided in the Linux operating system that indicates in a relative way how fast the computer processor runs. The program that provides the measurement is called BogoMips. Written by Linus Torvalds, the main developer of Linux, BogoMips can indicate when you boot a computer whether the system options have been specified for optimum performance. You compare the bogomips for your computer with what they ought to be for your computer's particular type of processor. Torvalds named the program BogoMips (for "bogus (or fake) MIPs") to suggest that performance measurements between two computers can be misleading because not all contributing factors are stated or even understood. Although MIPS (millions of instructions per second) has been frequently used in computer benchmarks, it's agreed that the variation of context tends to make the measurement misleading. Bogomips measures how many times the processor goes through a particular programming loop in a second.

BogoMIPS is built into some versions of Linux. It also exists as a stand-alone application program that you can download from certain Web sites. In October, 2001, Wintermute, a self-declared hacker site, reported that its server had achieved 2785.28 bogomips on a computer with an AMD Athlon microprocessor operating at 1,396 MHz"

@yoodoo: "1200 on A1-G3 @ 600 MHz"

On my Duron @ 600 MHz, using SuSE, I get 1196. I think the Duron is probably fairly similar to the G3 in state-of-development?

Your G3 beats my Duron by 5.8%

I guess itll take some time till we reach values like 4 x 5570 from this little beauty here (quad 2,8ghz)  :-D

I don't know anybody who actually uses bogomips for anything. They're pretty useless except for sometimes finding that one of your CPUs isn't running at the right clock speed for some reason.

I dont think bogomips say anything about the perfomance at all.. From what i heard, its same no matter what cpu you have, a 1ghz pIII and a 1ghz athlon has same...

Im not really sure about this though, but thats what someone told me.

Correct... For Pentium or greater x86 architecture, or PowerPC/Power4, bogomips's just actual measured mhz*2.  So according to that, my AMD 1.25ghz (which runs at 1.2611 for some strange reason) would score 2522.2 bogomips.  Hooray for useless numbers!
