It is not constructed at all.  It was the first thing I wrote down trying
to play a bit with speed.

Even the telco benchmark (where there's a lot of other stuff going
on) slows down by around 7-8%.

I did not hunt for these benchmarks. They are the first things I tried out.  I
cannot believe that you never saw a slowdown as claimed in your OP.
