PIE certain is better than nothing.  But it's no fq_codel.

All I varied between the two is the queuing discipline, with the PIE target
(both directions) set to 16ms.

not impressed.

But, far better than pie did when I was in Paris, on a 16Mbps down, 1Mbps
up ADSL2+ link:

I think those results were either the default target being wrong, or the
highly asynchronous and highly limited setup being ill-suited to PIE.
 Which is concerning, as PIE is going to be deployed in 30/1 cable setups
(like the Numericable.fr setup I had in my first apartment in Paris).
