The results in my mail were mean values over 2 runs,
only once did I see really huge (more than 10%) differences between several

FYI, 2 is not really enough, you should do at least 10 repetitions of each
test to reduce variance (which can be a lot, despite what you saw!) and so
that differences between them can be accurately estimated. Ministat is
really helpful for this.
Typically, I do 12 runs of supersmack in each configuration, and discard the
first 2 runs in which the cache and scheduler (etc) are still settling, as I'm
interested in the steady state.
