Does your posting of the benchmarks now imply that you re-created that
code? If so, may I take a look at it now?
I am surprised that "it wasn't much of effort". This suggests that you
did it only partially, and I'd like to see what you did vs. did not do,
to know what those benchmarks actually correspond to.
Thanks,
Alexander
