Your answer follows (look at the pathnames):

Richard, perhaps a few runs with a profiling-instrumented kernel (the IKD
patch provides this I think?) would be instructive. It would also be
useful if the span of the tests was less than 15 kernel revisions; is the
degradation "creeping", or does it jump in particular versions?
mean([322,355,362,328,311,306,329,341,332]) = 331.7778
var([322,355,362,328,311,306,329,341,332]) = 343.9444
std([322,355,362,328,311,306,329,341,332]) = 18.5457
mean([416,408,398,328,422,432,381,396,398]) = 397.6667
var([416,408,398,328,422,432,381,396,398]) = 918.5000
std([416,408,398,328,422,432,381,396,398]) = 30.3068
Interesting that the increase in standard deviation is disproportionate
with the increase of the mean... hmm...
