As a random data point, I tried a single flow from my main server in .no
to my backup server in .nl and compared CUBIC (with sch_fq) to BBR (naturally
also in sch_fq) on the sender side. The results were quite consistent across
runs:

 - BBR ramped up much quicker than CUBIC.
 - BBR gave ~10% higher max speed than CUBIC (~680 Mbit/sec on a gigabit link).
 - CUBIC wavered a bit up and down (~100 Mbit/sec) from the max; BBR stayed
   put (perhaps 2 Mbit/sec difference) the entire time.

graphs, sorry :-)
