The general idea of coming up with a way to benchmark these things is excellent and the OP is a worthy effort to get started.
Thanks for that effort.
Hopefully somebody can set up such a test using our code base.
Unfortunately we're launching two real-time blockchains this month (BitShares and PeerTracks' MUSE) so we're a bit busy.
But we'll be keeping tabs on how this goes.
Thanks
Stan
