Well, I've truly botched that. After adding backslashes to make the routines real code refs, and after commenting out the print statements, here are the new numbers: 

-bash-3.00$ perl -w db2test1.pl 
              Rate     bndEval   bndNoEval   noBndEval noBndNoEval
bndEval     114/s          --        -20%        -30%         -30%
bndNoEval   143/s         26%          --        -11%         -11%
noBndEval   161/s         42%         13%          --          -0%
noBndNoEval 161/s         42%         13%          0%           --

Now the results are a) statistically relevant and b) ordered more the way I first expected, with the no binding and no eval choice running as the fastest method.
