(Sigh. I just can help myself, can I? Always with the advice... ;-)

Two suggestions for using Benchmark:

If you're using long names for each test, pad the names to the same length with extra spaces on the left. Then your results are much easier to read and compare:

            Hash Exists Hit:  4 wallclock secs @ 1204819.28/s (n=10000
+00)
           Hash Defined Hit:  3 wallclock secs @ 2173913.04/s (n=10000
+00)
           Hash Exists Miss:  1 wallclock secs @ 1515151.52/s (n=10000
+00)
          Hash Defined Miss:  3 wallclock secs @ 1492537.31/s (n=10000
+00)
   Hash Assigned Miss Truth:  6 wallclock secs @ 1515151.52/s (n=10000
+00)
 Hash Assigned Hit Equality:  4 wallclock secs @ 1149425.29/s (n=10000
+00)
    Hash Assigned Hit Truth:  5 wallclock secs @ 970873.79/s (n=100000
+0)
Hash Assigned Miss Equality:  6 wallclock secs @ 877192.98/s (n=100000
+0)

Use cmpthese instead of timethese. That adds a handy comparison matrix at the end of your test results (though this suggestion works much better with shorter names):

          Rate  HDH HAHE HAME  HEH HAMT  HDM HAHT  HEM
HDH  1111111/s   --  -0%  -4% -21% -24% -28% -30% -39%
HAHE 1111111/s   0%   --  -4% -21% -24% -28% -30% -39%
HAME 1162791/s   5%   5%   -- -17% -21% -24% -27% -36%
HEH  1408451/s  27%  27%  21%   --  -4%  -8% -11% -23%
HAMT 1470588/s  32%  32%  26%   4%   --  -4%  -7% -19%
HDM  1538462/s  38%  38%  32%   9%   5%   --  -3% -15%
HAHT 1587302/s  43%  43%  37%  13%   8%   3%   -- -13%
HEM  1818182/s  64%  64%  56%  29%  24%  18%  15%   --
