Let me add that there are only two reasons for paying attention
to the BogoMips rating that is presented on booting Linux:
To see whether it is in the proper range for the particular
processor, its clock frequency, and the potentially present
cache. Many CPUs are prone to faulty setups of
memory cache setting (write-back is wrong for BogoMips, often
reported lower than 5; write-through is ok)
turbo-buttons (should be ON)
BIOS-software emulated fake cache (change it for real cache)
similar cache and clock related things, sometimes
also BIOS-software related
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? :-)
Note that more serious uses for real benchmarking are
addressed in the Linux Benchmarking Howto by André D. Balsa.
