I think these results are the only one that could be statisically significant:
base %stdev patched %stdev %improvement
kernbench 1x 53.1421 2.3086 54.6671 2.9673 -2.86966
dbench 1x 6386.4737 1.0487 6703.9113 1.2298 4.97047
and, of course :) one of them says things get worse and the other
says things get better.
