Do these numbers actually mean anything? You run one of these
benchmarks every single time a kernel comes out, there is always
minute differences in the numbers, but nothinging changes in the
kernel except long --> _u32 or networking fixes or such. How does that
explain all the differences in your numbers? Do you just run the test
when you feel like it without reguard to what is swapped in or out? Do
you neglect to flush the disk cache? Are you the only user online when
you run them? 1.3.11 is an exception if you install that experimental
patch linus gave, but for all the others I have to wonder why your
tests show a variation when there is no kernel changes to support
them.
I think what you are really showing us is either a) testing conditions
with too few constants or b) the margin of error for your testing
program.
