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.
