    SubjectRe: OSDL Scalable Test Platform test for linux_2_4_13
    From
    Date
      A couple of items explain these differences. The 1st is that 
    UnixBench is a single stream number and is almost 100% cached even
    with a smaller (128KB) cache. Also the benchmark uses a very small
    amount of memory. This means that for any given version
    of the compiler and OS the best absolute performance number will
    be produced by the machine with the fastest single CPU. And
    you won't see any improvement from adding additional CPUS.

    So what you are seeing is the difference between a single CPU
    running at 866MHz on the 2 way and a single CPU running at
    700 MHz on the 4 way. And of course your 1.4GHz would give better
    numbers as you are looking at 700Mhz, 866MHz and then 1.4 GHz and
    so the numbers should be

    The idea behind this test setup isn't to compare machine x
    verses machine y. (That's what marketing departments do.)
    But to be able to compare the same hardware against its self
    before and after a kernel change.
