-------------------------------------------------------------------------------
1. What are BogoMips

>From Lars Wirzenius' <wirzeniu@kruuna.Helsinki.FI> mail 
of 9 September 1993, explaining Bogomips:

   `MIPS is short for Millions of Instructions Per Second.
   It is a measure for the computation speed of a program.
   Like most such measures, it is more often abused than
   used properly (it is very difficult to justly compare
   MIPS for different kinds of computers).

   BogoMips are Linus's invention. The kernel (or was it a
   device driver?) needs a timing loop (the time is too
   short and/or needs to be too exact for a non-busy-loop
   method of waiting), which must be calibrated to the
   processor speed of the machine. Hence, the kernel
   measures at boot time how fast a certain kind of busy
   loop runs on a computer. "Bogo" comes from "bogus", i.e,
   something which is a fake. Hence, the BogoMips value
   gives some indication of the processor speed, but it is
   way too unscientific to be called anything but BogoMips.

   The reasons (there are two) it is printed during bootup
   is that a) it is slightly useful for debugging and for
   checking that the computers caches and turbo button work,
   and b) Linus loves to chuckle when he sees confused
   people on the news.'


-------------------------------------------------------------------------------
2. How to estimate BogoMips

>From a initiative by Ian Jackson <ijackson@nyx.cs.du.edu> and
Przemek Klosowski, much updated and expanded by Wim van Dorst for 
current data, as listed below:

   As a very approximate guide the BogoMips can be calculated by:

     System             BogoMips                           Comparison
     Intel 8088         clock * (0.004 plusminus 0.001)     0.02
     Intel/AMD 386SX    clock * (0.14  plusminus 0.01)      0.8
     Intel/AMD 386DX    clock * (0.18  plusminus 0.01)      1 (definition)
     Motorola 68030     clock * (0.25  plusminus 0.005)     1.4
     Cyrix/IBM 486      clock * (0.34  plusminus 0.065)     1.8
     Intel Pentium      clock * (0.40  plusminus 0.035)     2.2
     Intel/AMD 486      clock * (0.50  plusminus 0.01)      2.8
     Mips R4000/R4400   clock * (0.50  plusminus 0.015)     2.3
     PowerPC 601        clock * (0.77  plusminus 0.015)     4.5
     Alpha 21064/21066  clock * (0.99  plusminus 0.005)     5.5
     Mips R4600         (insufficient data yet)
     Motorola 68040     (insufficient data yet)
     Sparc              (insufficient data yet)

   Note that the BogoMips calculation loop is not optimized
   for the parallelism of the Pentium processor. 
   Note that the BogoMips calculation loop for the non-Intel
   CPUs is similar but not linearly equivalent.


-------------------------------------------------------------------------------
3. Variations in BogoMips rating

>From Linus Torvalds <torvalds@cc.helsinki.fi>, explaining about the 
variation one may see in the BogoMips rating, in c.o.l.development, 
at 28 April 1994

   `The BogoMips calculation loop is "quantizised", so you're
   most likely to get the exact same number all the time.
   You usually will get different numbers only if the speed
   is just on the "edge", when small variations (different
   time for interrupt ticks etc) will make it jump from one
   value to the other.'


-------------------------------------------------------------------------------
4. Standalone BogoMips program

>From the readme file of the standalone BogoMips program
by Jeff Tranter <jeff_tranter@mitel.com>:

   `Tired of rebooting your system so you can see how many
   BogoMIPS it's running at today?  [...] "Bogomips" is a
   standalone program that displays your system performance
   using one of the world's most recognized benchmarks.  It
   uses the same code that is used in the Linux kernel while
   booting, but runs as a user program. [...] Version 1.3 of
   BogoMIPs is now portable and should run on any system
   that supports an ANSI C compiler and library.'

   Note that due to system load values calculated with the
   standalone program may be lower than registered in the 
   list below.


-------------------------------------------------------------------------------
5. BogoMips ... failed

Suggested by various questions on the net and private mail, 
e.g. by Lily <lbliao@alumni.caltech.edu> and by Pierre Frenkiel 
<frenkiel@cdfap2.in2p3.fr>. In March 1995 they asked:

   `When I boot Linux I get the message:
      Calibrating delay loop.. ok - 23.96 BogoMips
      failed
   Where/why has the calibration delay loop failed?'
 
   It didn't fail. If it had failed the text would have been
      Calibrating delay loop.. failed

   What likely did fail was a driver for some gadget which
   you may not have in your machine. Just after calculating
   the BogoMips rating all device drivers are initiated.
   First the SCSI devices, then Net devices, etc.  Any
   failure is duly reported. Noteworthy is the AHA152x
   driver. Other effects of failing drivers (and not of
   failing BogoMips calculations) are systems crashes, long
   waits, and complete system locks.

   Since Linux 1.2 many error messages have improved, so
   upgrade to at least that version to find out which
   particular driver it is that is failing.


-------------------------------------------------------------------------------
6. Why to pay attention to BogoMips

Let me add that there are only two reasons for paying attention
to the BogoMips rating that is presented on booting Linux:

   1. To see whether it is in the proper range for the
      particular processor, its clock frequency, and the
      potentially present cache. Especially 486 systems are
      prone to faulty setups of RAM caching, turbo-buttons,
      and such things.

   2. To see whether your system is faster than mine. Of
      course this is completely wrong, unreliable,
      ill-founded, and utterly useless, but all benchmarks
      suffer from this same problem. So why not use it? This
      inherent stupidity has never before stopped people
      from using benchmarks, has it? :-)


-------------------------------------------------------------------------------

Isolde is rapidly growing to be a full toddler: "drawing," riding
tricycles and dancing are her greatest hobbies. Walking about in
her winter coat and a shawl she looks like a Michelin man, but
she enjoys the cold and the ice, apart from the running nose.
Look in Linux Journal for a cute picture of her.

Met vriendelijke groeten, Wim van Dorst.
