The script is good, thanks for taking the time.  But your results are
strange (especially the 30% improvement of get method).  Here's what I
get:

             $ret = ...         void context

trunk        101.255008          102.128995
              13.434119           13.074898

noreply       97.261798           13.326187
              12.990013           12.990013


I don't see the overhead of assignment BTW, numbers are roughly the
same.  So my questions are: are you sure patched Perl module was used
instead of a system-wide one (you probably have to set PERL5LIB)?
Have you rebuild and restarted the server?

But you added 'noreply' manually, right?


Sorry for such questions, but I can't find explanation to your results
at all.
