It would be very very useful to post such benchmarks. A negative result
is still a result! You put time and effort to investigate a design. Even
if the conclusion is "the design isn't good", it would be great to leave
a written trace so that if someone comes up with a similar idea can
"stand on the shoulders of giants" and build from there.
